Question

Use stoichiometric principles combined with the ideal gas law to solve for quantities in reactions involving gases.

a) True
b) False

Answer 1

Gas stoichiometry involves using stoichiometric principles along with the ideal gas law to solve for quantities in reactions involving gases. By applying the ideal gas law and using stoichiometry, we can calculate the amounts of reactants and products in a gas-phase chemical reaction.

Step-by-step explanation:

Gas stoichiometry involves using stoichiometric principles along with the ideal gas law to solve for quantities in reactions involving gases. The ideal gas law, PV = nRT, relates the pressure, volume, temperature, and number of moles of a gas. By applying this law and using stoichiometry, we can calculate the amounts of reactants and products in a gas-phase chemical reaction.

For example, if we have a reaction where one of the reactants is a gas, we can use the ideal gas law to calculate the number of moles of that gas. Then, using stoichiometry, we can determine the amount of another reactant or the amount of product formed.

To solve gas stoichiometry problems, follow these steps:

1. Write the balanced chemical equation for the reaction.
2. Convert the given quantities (volume, pressure, temperature) to the appropriate units (moles, liters, kelvin).
3. Use the ideal gas law to calculate the number of moles of a gas reactant or product.
4. Apply stoichiometry to determine the desired quantity of another reactant or product.
