When gases react according to a balanced chemical equation, such as:
2H2(g) + O2 (g) → 2 H2O(g) , what do the coefficients represent?
A) The gas masses that react
B) The gas pressures that react
C) The gas volumes that react
D) None of the above
Balanced Chemical Equation
A symbolic representation of a chemical reaction in which the number of atoms for each element is equal on both the reactant and product sides.
Coefficients
Numerical or constant multipliers that are placed before variables in equations to denote how many units of the variable are involved.

Final Answer :
C
Explanation :
The coefficients in a balanced chemical equation represent the relative volumes of gases that react, assuming all gases are at the same temperature and pressure. This is based on Avogadro's law, which states that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules.
