What three factors must be considered in writing a balanced chemical equation?
From the reference: (1) Apply the Law of Conservation of Mass to get the same number of atoms of every element on each side of the equation. Tip: Start by balancing an element that appears in only one reactant and product. (2) Once one element is balanced, proceed to balance another, and another, until all elements are balanced. (3) Balance chemical formulas by placing coefficients in front of them. Do not add subscripts, because this will change the formulas.
