Given The Equation: 2h2 + O2 2h2o If Given 10g H2 Gas And 15g O2 Gas What Is The Limiting Reactant

Molar Mass / Molecular Weight of CaSO4 2H2O : Calcium sulfate dihydrate

Start by taking a look at the balanced chemical equation for this reaction

#color”H”_text + “O”_text -> 2″H”_2″O”_text#

Notice that you have a #color:1# mole ratio between hydrogen gas and oxygen gas.

This means that, regardless of how many moles of oxygen gas you have, the reaction needs twice as many moles of hydrogen gas in order to proceed.

You know that you start with #”10.0 g”# of hydrogen gas nad #”15.0 g”# of oxygen. To determine how many moles of each you have, use their respective molar masses

#10.0color)) * /))) = “4.961 moles H”_2#

#15.0color)) * /))) = “0.4688 moles O”_2#

Notice that you have quite a significant difference, way bigger than the required #color:1# ratio needed, between how many moles of hydrogen gas and how many moles of oxygen you have.

This means that you’re dealing with a limiting reagent. How many moles of oxygen would have been needed to react with all the hydrogen?

#4.961color)) * /color))) = “2.4805 moles O”_2#

Since you don’t have that many moles of oxygen, it follows that oxygen is your limiting reagent, i.e. it will determine how much hydrogen reacts and how much remains in excess.

For example, how many moles of hydrogen gas would react if you have #0.4688#

#0.4688color)) * ” moles H”_2)/))) = “0.9376 moles H”_2#

The rest of the hydrogen will be in excess.

More Information Onmolar Mass And Molecular Weight

In chemistry, the formula weight is a quantity computed by multiplying the atomic weight of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together.

Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. These relative weights computed from the chemical equation are sometimes called equation weights.

A common request on this site is to convert grams to moles. To complete this calculation, you have to know what substance you are trying to convert. The reason is that the molar mass of the substance affects the conversion. This site explains how to find molar mass.

If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom in the formula by the formula weight and multiplying by 100.

Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance.

Finding molar mass starts with units of grams per mole . When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula.

Effect On Biological Systems

Different isotopes of chemical elements have slightly different chemical behaviors, but for most elements the differences are far too small to have a biological effect. In the case of hydrogen, larger differences in chemical properties among protium , deuterium, and tritium occur, because chemical bond energy depends on the reduced mass of the nucleuselectron system this is altered in heavy-hydrogen compounds more than for heavy-isotope substitution involving other chemical elements. The isotope effects are especially relevant in biological systems, which are very sensitive to even the smaller changes, due to isotopically influenced properties of water when it acts as a solvent.

Heavy water affects the period of circadian oscillations, consistently increasing the length of each cycle. The effect has been demonstrated in unicellular organisms, green plants, isopods, insects, birds, mice, and hamsters. The mechanism is unknown.

To perform their tasks, enzymes rely on their finely tuned networks of hydrogen bonds, both in the active center with their substrates, and outside the active center, to stabilize their tertiary structures. As a hydrogen bond with deuterium is slightly stronger than one involving ordinary hydrogen, in a highly deuterated environment, some normal reactions in cells are disrupted.

Other Heavy Forms Of Water

Semiheavy water, HDO, exists whenever there is water with light hydrogen and deuterium in the mix. This is because hydrogen atoms are rapidly exchanged between water molecules. Water containing 50% H and 50% D in its hydrogen actually contains about 50% HDO and 25% each of H2O and D2O, in dynamic equilibrium.In normal water, about 1 molecule in 3,200 is HDO , and heavy water molecules only occur in a proportion of about 1 molecule in 41 million . Thus semiheavy water molecules are far more common than “pure” heavy water molecules.

O is also commercially available, e.g., for use as a non-radioactive isotopic tracer. It is “heavy water” as it is denser than normal water but is rarely called heavy water, since it does not contain the deuterium that gives D2O its unusual nuclear and biological properties. It is more expensive than D2O due to the more difficult separation of 17O and 18O. H218O is also used for production of fluorine-18 for radiopharmaceuticals and radiotracers and for positron emission tomography. Small amounts of 17O and 18O are naturally present in water and most processes enriching heavy water also enrich the heavier isotopes of oxygen as a side-effect. This is undesirable if the heavy water is to be used as a neutron moderator in nuclear reactors, as 17O can undergo neutron capture followed by emission of an alpha particle producing radioactive 14C

What Is The Chemical Name Of Gypsum

Molar Mass / Molecular Weight of CaSO4 . 2H2O

Its chemical name is calcium sulfate dihydrate .

Gypsum can be mixed with water and restored to its original rock-like condition. This means it can be more rigid. It has a closed recycling loop that can be reused indefinitely while maintaining high quality.

An alternative to natural gypsum is flue gas desulfurization gypsum or FGD gypsum. It is a by-product of coal-fired power plants.

What are the uses of gypsum?

Gypsum is used for the renovation and construction of all types of residential and non-residential buildings. It can be used for very beautiful, contemporary designs and structures, as well as simple everyday objects and processes.

European building interiors use about 5 million tones of gypsum-based plaster every year. European interior surfaces over 1,500 million square meters

Gypsum uses include: wallboard, cement, plaster of Paris, soil conditioning, and hardening of Portland cement. The varieties of gypsum are known as satin spar and alabaster for a variety of ornamental purposes however, their low hardness limits their durability.

Some examples of gypsum:

Plaster board

Plasterboard is used for the partitioning and lining of walls, ceilings, ceilings and floors. Gypsum is an important component of modern plasterboard.

Gypsum fiberboard

Heavy Water Radiation Contamination Confusion

Although many people associate heavy water primarily with its use in nuclear reactors, pure heavy water is not radioactive. Commercial-grade heavy water is slightly radioactive due to the presence of minute traces of natural tritium, but the same is true of ordinary water. Heavy water that has been used as a coolant in nuclear power plants contains substantially more tritium as a result of neutron bombardment of the deuterium in the heavy water .

In 1990, a disgruntled employee at the Point Lepreau Nuclear Generating Station in Canada obtained a sample of heavy water from the primary heat transport loop of the nuclear reactor, and loaded it into a cafeteria drink dispenser. Eight employees drank some of the contaminated water. The incident was discovered when employees began leaving bioassay urine samples with elevated tritium levels. The quantity of heavy water involved was far below levels that could induce heavy water toxicity, but several employees received elevated radiation doses from tritium and neutron-activated chemicals in the water. This was not an incident of heavy water poisoning, but rather radiation poisoning from other isotopes in the heavy water.

Metabolic Rate Testing In Physiology And Biology

Tritium is the active substance in self-powered lighting and controlled nuclear fusion, its other uses including autoradiography and radioactive labeling. It is also used in nuclear weapon design for boosted fission weapons and initiators. Tritium undergoes beta decay into Helium-3, which is a stable but rare isotope of Helium that is itself highly sought after. Some tritium is created in heavy water moderated reactors when deuterium captures a neutron. This reaction has a small cross-section and produces only small amounts of tritium, although enough to justify cleaning tritium from the moderator every few years to reduce the environmental risk of tritium escape.

Producing a lot of tritium in this way would require reactors with very high neutron fluxes, or with a very high proportion of heavy water to nuclear fuel and very low neutron absorption by other reactor material. The tritium would then have to be recovered by isotope separation from a much larger quantity of deuterium, unlike production from lithium-6 , where only chemical separation is needed.

How Do You Balance H2o2 H2o O2

Moisture out the tailpipe, sign of cracked head?

Explanation: This reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen. Add 2 molecules of hydrogen peroxide and 2 molecules of water. Since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

Why Does Combining Hydrogen And Oxygen Typically Produce Water Rather Than Hydrogen Peroxide

Molar Mass / Molecular Weight of BaCl2 2H2O

Chemists Joel Rosenthal and Daniel G. Nocera of the Massachusetts Institute of Technology provide this answer.

When molecular hydrogen and oxygen are combined and allowed to react together, energy is released and the molecules of hydrogen and oxygen can combine to form either water or hydrogen peroxide. These two processes are represented by the two chemical equations shown at right. Chemists use redox half-reactions to describe thermodynamic processes like the ones embodied by such equations. For both of the reactions shown, the hydrogen molecules are oxidized and the oxygen atoms are reduced. Accordingly, each of the reactions below is described by a combination of two half-reactions–one corresponding to a chemical oxidation and another corresponding to a reduction.
