The answer is: 4) The same subscripts are on each side of the equation.For example, the balanced chemical reaction: 2mg + O₂ → 2MgO. 1) The same number of atoms on each side of the equation: two atoms of magnesium and two oxgen atoms.2) The formulas for all substances are correct: in magnesium oxide (MgO), magnesium has an oxidation number of +2 and oxygen is -2, so the formula is good, because the compound must be neutral.3) The same mass is represented on each side of the equation: because there is the same number of atoms, the mass is the same.4) The same subscripts are on each side of the equation: the oxygen does not have the same subscripts.
