Answer 2

The reactant that runs out first, stopping the entire reaction

Question 3

Stoichiometric Coefficients

Answer 3

The number that appear to the left of each substance

Question 4

Gay-Lussac’s Law

Answer 4

The stoichiometric coefficients in a chemical equation relate the volumes (in liters) of gasses in the equation as well as the number of moles of substances in the equation

Question 5

When can Gay-Lussac’s law be implemented in stoichiometry?

Answer 5

Gay-Lussac’s law can be used in stoichiometry only if everything you are using in the problem is gas
