What Does Co Stand For In Chemistry

Bond Polarity And Oxidation State

Theoretical and experimental studies show that, despite the greater electronegativity of oxygen, the dipole moment points from the more-negative carbon end to the more-positive oxygen end. The three bonds are in fact polar covalent bonds that are strongly polarized. The calculated polarization toward the oxygen atom is 71% for the -bond and 77% for both -bonds.

The oxidation state of carbon in carbon monoxide is +2 in each of these structures. It is calculated by counting all the bonding electrons as belonging to the more electronegative oxygen. Only the two non-bonding electrons on carbon are assigned to carbon. In this count, carbon then has only two valence electrons in the molecule compared to four in the free atom.

Carbon monoxide occurs in various natural and artificial environments. Typical concentrations in parts per million are as follows:

Composition of dry atmosphere, by volume

Carbon monoxide has an indirect effect on radiative forcing by elevating concentrations of direct greenhouse gases, including methane and troposphericozone. CO can react chemically with other atmospheric constituents ” rel=”nofollow”>radical, OH.) that would otherwise destroy methane. Through natural processes in the atmosphere, it is oxidized to carbon dioxide and ozone. Carbon monoxide is short-lived in the atmosphere , and spatially variable in concentration.

Thc And Recreational Cannabis Use

Despite its medicinal properties, THCs claim to fame is the euphoric high it produces. Recreational use of marijuana is all about dialing in the perfect ratio of effects for each individual. And the recreational market, especially where its above ground, continues to develop new and innovative ways of getting high.

Whether its new strains boasting previous unheard of THC concentrations, new devices for obtaining and consuming cannabis concentrates, or new techniques for produces the highest quality edibles, the recreational market is no doubt one of the most exciting emerging horizons in the cannabis industry worldwide.

At the moment, no trend dominates the recreational cannabis scene more than concentrates. So what is THC concentrate?

What Is Thc And What Does It Do

Throughout its life, a cannabis plant will produce more than 400 different chemical compounds. But the presence of just one of those hundreds of compounds has sealed cannabis fate for nearly a century, making it one of the most persecuted plants on the planet. And all because this one compound happens to interact with the human body in such a way as to produce a complex signature of effectsa high unlike any other. Its name is THC. What is THC and what does THC stand for? Tetrahydrocannabinol. More importantly, what does THC do to the brain?

THC is one of the 113 chemical compounds found only in the plant genus Cannabis, which scientists call cannabinoids. THC, however, is unique among all the rest for one, massively important reason: its the most potently psychoactive.

But exactly what is THC, and why does it produce the wide range of pleasurable effects it does? What does THC do to the brain? How does it affect the body? Is it safe, or as dangerous as heroin, like the federal government says?

Decades of unanswered questions, confusion, and misinformation have distorted the publics understanding of cannabis and the psychoactive cannabinoid that has made it the most popular illicit drug in the world.

Using Ka And Pka To Predict Equilibrium And Strength Of Acids

Ka may be used to measure the position of equilibrium:

• If Ka is large, the formation of the products of the dissociation is favored.
• If Ka is small, the undissolved acid is favored.

Ka may be used to predict the strength of an acid:

• If Ka is large this means the acid is mostly dissociated, so the acid is strong. Acids with a pKa less than around -2 are strong acids.
• If Ka is small , little dissociation has occurred, so the acid is weak. Acids with a pKa in the range of -2 to 12 in water are weak acids.

Ka is a better measure of the strength of an acid than pH because adding water to an acid solution doesn’t change its acid equilibrium constant, but does alter the H+ ion concentration and pH.

Fire It Up Why You Need Heat To Enjoy Thc

Since weve taken a good look at the recreational dimensions of tetrahydrocannabinol, nows a good time to mention a very important fact about consuming THC.

In its raw form, tetrahydrocannabinol is totally inert and will do nothing for you. Again, the form in which tetrahydrocannabinol manifests in cannabis plants is inactive. If you ate a handful of dried cannabis flowers, you wouldnt get high. But you would have a stomach ache trying to digest the plant fibers! You need heat to make tetrahydrocannabinol work!

So what does THC do when you apply heat to it.

Technically speaking, the cannabinoid that appears in cannabis is THCA. The A designates its acidic form. It takes heat to convert THCA to the psychoactive delta-9 tetrahydrocannabinol. Thats why you have to apply a flame to dried cannabis. Not just to combust the buds to produce smoke to inhale, but to actually activate the THC.

That activation process is called , or decarb for short. Decarbing your cannabis is an absolutely indispensable step when making edibles. Without it, youre just eating a bunch of raw THCA.

But heating THC to the point of decarboxylation is challenging. Its too easy to apply too much heat, which results in boiling off the tetrahydrocannabinol completely. Not good!

How Thc Gets You High

CB1 receptors throughout the brain and nervous system modulate movement, memory, cognition, sensory perceptions, and even time perception. According to NIDA, tetrahydrocannabinol over activates the functions typically regulated by the ECS, like mood, appetite, cognition, and perception.

Ultimately, its the sum total of all of these changes that creates the overall sensation we love to call being high. And it accounts for why everyones high is unique, and why highs can vary from buzzed to baked to way, way too high. There are just so many factors at play. Changes that feel good to someone might make someone else feel uncomfortable.

Then, there are the more mysterious effects of delta-9-THC on the brain. Remember anandamide, our bodys own version of THC? Researchers believe anandamide may have something to do with our brains ability to forget.

At first glance, this fact seems to confirm the oft-cited concern that cannabis use reduces short-term memory capabilities. Yet the power to forget can be incredibly beneficial for those suffering from traumatic memories, like people with PTSD. Hence the promising findings that tetrahydrocannabinol can treat a range of psychological disorders related to trauma.

Acid Dissociation Constant From Ph

The acid dissociation constant may be found it the pH is known. For example:

Calculate the acid dissociation constant Ka for a 0.2 M aqueous solution of propionic acid that is found to have a pH value of 4.88.

To solve the problem, first, write the chemical equation for the reaction. You should be able to recognize propionic acid is a weak acid . It’s dissociation in water is:

CH3CH2CO2H + H2 H3O+ + CH3CH2CO2-

Set up a table to keep track of the initial conditions, change in conditions, and equilibrium concentration of the species. This is sometimes called an ICE table:

Origins Of The Periodic Table Of Elements

The Periodic Table displays all known chemical elements which are grouped by chemical properties and atomic structure.

Copper, silver, gold, mercury, tin, lead, and other elements have been known since ancient times and were used to make jewelry, coins, and tools. Phosphorus became the first element to be discovered by Hennig Brand in 1649. It is known as the first scientific discovery of a chemical element.

Thc : The Fundamentals Of Tetrahydrocannabinol

Lets start with the basics: what is THC and what does THC stand for?

THC is an acronym for the unwieldy and eight-syllable full name of the chemical compound in weed that makes you high. Tetrahydrocannabinol. Its chemical name is -trans-delta 9-tetrahydrocannabinol if you want to get really technical.

The word is imposing at first, but with a little practice, youll find it rolls off the tongue. Its elegance is in its meter, three trochees followed by an iambic flourish. TE-tra-HY-dro-CAN-na-bin-OL. See? Easy!

Now that you sound like an expert, lets actually make you into one. Heres your fundamental fact sheet about THC.

The Most Abundant Element In The Universe

About 75 percent of the mass of the universe consists of hydrogen, making it the most abundant element. It is a colorless and odorless gas that makes up nuclear matter. The second most abundant is helium, which accounts for about 25 percent of the mass. Other elements include oxygen, iron, neon, magnesium, carbon, and nitrogen.

Nomenclature Of Optical Isomers

Various methods have been used to denote the absolute configuration of optical isomers such as R or S, Î or Î, or C and A. The IUPAC rules suggest that for general octahedral complexes C/A scheme is convenient to use and that for bis and tris bidentate complexes the absolute configuration be designated Lambda Î and Delta Î .

Priorities are assigned for mononuclear coordination systems based on the standard sequence rules developed for enantiomeric carbon compounds by Cahn, Ingold and Prelog . These rules use the coordinating atom to arrange the ligands into a priority order such that the highest atomic number gives the highest priority number . For example the hypothetical complex 2- would assign the I- as 1, Br as 2, Cl as 3, SCN as 4, NO2 as 5 and NH3 as 6.

Figure \: Here is one isomer where the I and Cl, and Br and NO2 were found to be trans- to each other.

The reference axis for an octahedral center is that axis containing the ligating atom of CIP priority 1 and the trans ligating atom of lowest possible priority . The atoms in the coordination plane perpendicular to the reference axis are viewed from the ligand having that highest priority and the clockwise and anticlockwise sequences of priority numbers are compared. The structure is assigned the symbol C or A, according to whether the clockwise or anticlockwise sequence is lower at the first point of difference. In the example shown above this would be C.

What Is Epc And How Is It Different To Epcm

EPC stands for Engineering, Procurement and Construction so the crucially missing element is the M for Management. Simply put, this is because EPC is not a service in the same way that EPCM is. Think of EPC as more completely contracting-out the project, rather than having engineering consultants manage it for you.

So this means with an EPC contract, yes your engineers will completely handle the clients project from start to finish, however, the client effectively relinquishes control of the project from the moment the contract is signed. So the engineers then have complete ownership of the project from then on, and they make all the decisions, with no involvement of the client needed, nor transparency on those decisions.

Thc Concentrates And The Brave New World Of Dabbing

There are a few methods for extracting cannabinoids from the herbaceous matter of dried cannabis flowers. Some are safer than others. But the objective for each of them is the same: extract the maximum amount of cannabinoids and terpenes from the cannabis plant.

Butane, CO2 and alcohol extraction methods each have their own merits. And each is able to produce cannabis concentrates with THC concentration levels around 90 percent or higher. Compare that to the average of 25-30 percent THC boasted by the most potent cannabis strains, and you can see why concentrates have become so popular among recreational users.

In final form, concentrates are rich and flavorful substances with an amber color and sticky, gooey texture. They can be consumed purely, or mixed with edible waxes, oils and tinctures in the forms of beverages and tasty treats.

One method of consuming concentrates, however, has catapulted to popularity among recreational users: dabbing. Dabbing is the process of super-heating a glass or metallic element, placing a dab of concentrate on it, and inhaling the ensuing vapors.

Concentrate extraction removes all the bitter plant matter from the cannabis. Yet it maintains the presence of the plant terpenes that give cannabis its taste and smell. Hence, the experience of dabbing, or inhaling the vapor of sublimated concentrates, provides incomparably rich flavors compared to just smoking flowers.

Physical And Chemical Properties

Carbon monoxide is the simplest oxocarbon and is isoelectronic with other triply-bonded diatomic species possessing 10 valence electrons, including the cyanide anion, the nitrosonium cation, boron monofluoride and molecular nitrogen. It has a molar mass of 28.0, which, according to the ideal gas law, makes it slightly less dense than air, whose average molar mass is 28.8.

The carbon and oxygen are connected by a triple bond that consists of a net two pi bonds and one sigma bond. The bond length between the carbon atom and the oxygen atom is 112.8;pm. This bond length is consistent with a triple bond, as in molecular nitrogen , which has a similar bond length and nearly the same molecular mass. Carbonoxygen double bonds are significantly longer, 120.8;pm in formaldehyde, for example. The boiling point and melting point are very similar to those of N2 . The bond-dissociation energy of 1072;kJ/mol is stronger than that of N2 and represents the strongest chemical bond known.

The groundelectronic state of carbon monoxide is a singlet state since there are no unpaired electrons.

The Medicinal Benefits Of Tetrahydrocannabinol

Since THC has become synonymous with marijuana in our everyday lexicon, it can be easy to overlook or discount the medicinal benefits of the cannabinoid. And while its true that the chemical is highly prized by recreational users, researchers continue to identify innovative ways to use it as a medicine.

Thc And The Endocannabinoid System: The Secret To Why Youre High

Tetrahydrocannabinol? Endocannabinoid system? Understanding the biochemistry of cannabis definitely requires picking up some new vocabulary. But theyre key to understanding what THC is and how it affects us.

In fact, the key makes a good explanatory metaphor. The ECS is like a vast system of locks, or chemical receptors, and keys, the chemicals that bind to them. Some keys only work on a specific lock. Other keys fit in multiple locks. The human body has evolved to produce its own keys, or endogenous cannabinoids, for those locks.

If youre a runner, you already know all about this. That runners high you crave is caused by anandamide binding with cannabinoid receptors in your nervous system. Anandamide is THCs endogenous equivalent. Now thats getting high on your own supply!

Amazingly, the cannabinoids the cannabis plant produces happen to bind to those same receptors. Theyre keys from nature that fit the locks in our ECS. That doesnt mean humans evolved for cannabis, however. Rather, humans have taken advantage of the fact for enjoyment and health. And weve been doing it for millennia.

History Of The Abbreviations

In fact, there are eleven of the abbreviations for the elements which don’t seem to match the modern name. Those are subtle reminders of the history of the Periodic Table and the process of the discovery of elements over the millennia. Eight of these oddities are Au , Ag , Cu , FE , SN , Pb , Sb , and Hg : All were among the elements recognized by the ancient Greeks and Romans, and the abbreviations for those are based on a Latin or Greek term for the element.;

Potassium was identified during the Middle Ages, and it’s “K” is for kalium, a medieval Latin term for potash. W stands for tungsten because it was first identified in 1780 within the mineral known as wolframite, by French scientist Antoine Lavoisier . And finally, sodium gets an Na because it was first isolated by the English chemist Humphry Davy in 1807 and he was referring to natron, an Arabic word for the salt used by the Egyptians to mummify people.
