Unformatted text preview: v. Dalton theorized this to prove/explain previously formed laws 1. Law of definite proportions a. Like compounds always have like mass ratios between their elemental makeup (fixed composition) 2. Law of conservation of mass a. Mass of the reactants always equals the mass of the products vi. Law of Multiple Proportions 1. Atoms combining in one elemental ratio, then those same atoms combining in a different ratio produces a different compound...
