11. An old bike is left abandoned in a shed for many years, where it begins to rust. The bike is not exposed to rain or wind that would cause the rust to fall off the bike. Is the bike gaining mass, losing mass, or maintaining the same mass as it rusts? Explain. 12. Describe 2 factors that can reduce percent yield when a scientist is trying to create a specific chemical product. Explain specifically how each factor reduces percent yield. ( 13. How did decomposition reactions help early chemists come to the Law of Definite Proportions?

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
