Question
Chapter 6, Problem 6.74QE
Interpretation Introduction
Interpretation:
Mass of water formed when oxygen gas combines with hydrogen gas in the containers has to be calculated.
Concept Introduction:
In any stoichiometric balanced equation; the reactant that is present in the least amount and that governs the amount of products formed is known as limiting reactant.
Prior to the identification of the limiting reactant; a balanced equation is written, then the amount of each reactant in grams is converted to corresponding moles. Further on the basis of the stoichiometric molar ratio by which reactants combine, the amount of product formed from each of the reactants is calculated.
