Chemical Reactions with Isotopes

The coefficients in a balanced chemical equation represent the relative numbers of each molecule or formula unit and the relative number of moles of each molecule or formula unit. In a balanced equation, the stoichiometric relationships among the substances allow us to convert between quantities of reactants and products in a reaction.

Deuterium

Deuterium (written as D or 2H) is an isotope of hydrogen known as heavy hydrogen.

PART A QUESTION:

Balance the given chemical equation using whole-number coefficients.

?D2(g)+?O2(g)→?D2O(l)

Enter the coefficients in order separated by commas (e.g., 1,3,2, where 1 indicates the lack of a coefficient).

  • The coefficients in a balanced chemical equation provide the mole-to-mole stoichiometry among the reactants and products

    The coefficients in a balanced chemical equation provide the mole-to-mole stoichiometry among the reactants and products. The molar mass (in g/mol) can be used as the conversion factor between moles and the mass of a substance. Thus, the balanced equation and molar masses can be used in conjunction with one another to calculate the masses involved in a reaction. Part B What mass of carbon dioxide is produced from the complete combustion of 1.90x10-3 g of methane?Part C What mass of water is...

    Name: 2.2 Hydrogen The relative isotopic abundance for hydrogen 2H: 1H is about 0.00016: 1, and therefore hydrogen isotopic substitutions are unlikely to play a major role in any observed (M+1) peak. The isotope 2H is called "heavy hydrogen or deuterium, and is given the symbol D. We can often provide support for mechanisms by incorporating isotopes such as 13C or D into compounds using isotopically labelled reagents. Mass spectrometry is a useful tool for analyzing such isotopic incorporation by...
