Balancing Chemical Equations Worksheet 3 If you also find difficulty in balancing the chemical equations, follow the steps below. step # 1: write down the unbalanced equation. the first step to balance the equation is to write down the chemical formula of reactants that are listed on the left side of the chemical equation. after this, you can list down the products on the right hand. Balancing equations: answers to practice problems 1. balanced equations. (coefficients equal to one (1) do not need to be shown in your answers). (a) 2fe 3cl2 −−→2fecl3 (b) 4fe 3o2 −−→2fe2o3 (c) 2febr3 3h2so4 −−→ 1fe2(so4)3 6hbr (d) 1c4h6o3 1h2o −−→2c2h4o2 (e) 1c2h4 3o2 −−→2co2 2h2o (f) 1c4h10o 6o2 −−→. N 2 h2o this puts the hydrogen atoms out of balance. now there are two hydroge. atoms on the left and four hydrogen atoms on the right. to get four hydrogen atoms o. the right, add a coefficient of 2 for the hydrogen gas. remember, coefficients are multipliers, so if we write 2 h2. s and 2x1=2 oxygen atoms. s.
