Practice: The oxidation of chromium solid is represented by the following equation:
How many moles of chromium (III) oxide are produced when 34.69 g Cr reacts with excess oxygen gas?
Stoichiometry deals with the numerical relationship between compounds in a balanced chemical equation.
Concept #1: Stoichiometry
Concept #2: Stoichiometric Chart
Utilize the stoichiometric chart to do all your stoichiometric calculations.
Example #1: How many grams of H2O are produced when 12.3 g H2 reacts?
2 H2 (g) + 1 O2 (g) → 2 H2O (g)
