Match the term on the left box with the most appropriate definition on the right. 1 Empirical Formula A A compound with a specific number of water molecules bonded to each formula unit. 2 Mass Percent B This shows only the relative amounts of the elements, not the actual amounts. Atoms of an element are chemically similar but Chave different numbers of neutrons and, thus, different mass numbers. This represents an element in a compound is the D mass of the element expressed as a percentage of the total mass of the compound. E The study of mass-mole-number relationships in chemical reactions and formulas. F The reactant that runs out first following a chemical reaction. G The amount of substance contains as many elementary entities as exactly 12g of carbon-12. The law states that the elements in a chemical H compound are always present in the same proportions by mass. A compound that does not have any water I molecules bonded to it; applies to compounds that can be hydrated. J This…
