According to John Dalton's "Law of Conservation of Mass", mass cannot be created or destroyed. In any chemical reaction, the same type of atoms must appear on both sides of the equation, and in the same amount. Example: 2A +3X→ A2X3 reactants → products If I start with 2 atoms of A, and 3 atoms of X on the reactants side, then there must be 2 atoms of A, and 3 atoms of X on the products side to satisfy Dalton's law. If A has a mass of 4.50 g, and X has a mass of 5.35 g, then; 2(4.50 g) + 3(5.35g) = A2X3 9.00 g +16.05 g = (4.50)2 + (5.35) 25.05 g = 25.05 g Balance the following equations and indicate the reaction type for each one.
