Step 1

Step 1: We start by looking at the balanced chemical equation: $$ 2 \mathrm{C}_{2} \mathrm{H}_{6}(\mathrm{g})+7 \mathrm{O}_{2}(\mathrm{g}) \rightarrow 4 \mathrm{CO}_{2}(\mathrm{g})+6 \mathrm{H}_{2} \mathrm{O}(\mathrm{g}) $$ From this equation, we can see that 2 Show more…

Key Concepts

Avogadro's Law

Avogadro’s law states that equal volumes of gases at the same temperature and pressure contain the same number of molecules. This allows us to directly use the volume ratios from the balanced chemical equation in gas-phase reactions, so that the ratios of volumes are the same as the coefficients in the balanced equation.

Balanced Chemical Equation

A balanced chemical equation represents the conservation of mass by ensuring that the number of atoms for each element is equal on both the reactants and products sides of the reaction. This balance is crucial for accurately determining the relationships between reactants and products.

Stoichiometry

Stoichiometry is the calculation of reactants and products in chemical reactions based on the balanced chemical equation. It involves using the mole ratios derived from the equation to determine how much of one substance is needed or produced from a given amount of another substance.
