"Stoichiometry is the study of measuring or predicting the amount of reactants or products in a chemical reaction based on the variables such as the mass of reactants or products, the limiting reactan ...
"In a single replacement reaction, a single element replaces an atom in a compound producing a new compound and a pure element. Like double replacement reactions, metals always replace metals and nonm ...

"In a double replacement reaction, two compounds swap atoms forming two different compounds. Like single replacement reactions, metals always replace metals and nonmetals always replace nonmetals. Dou ...
"A decomposition reaction is a reaction in which a single reactant produces multiple products. An example of a decomposition reaction is when water is broken down into hydrogen and oxygen. In essence ...
