With enough practice, scientists can easily balance equations. So you are able to do the same, you are going to work out on paper what they can do in their head. For questions 1-5 below, an unbalanced chemical equation is provided. Use this equation to fill in the first table. balance the equation below it. Then fill in the second table with the balanced equation. Example: H2 + I2 → HI Use the table below to show the initial numbers of reactant and product atoms: Atoms on the left of the arrow Atoms on the right of the arrow 2 H 1 H 2 I 1 I Rewrite and balance the equation: H2 + I2 →2 HI Use the table below to show that the reaction is correctly balanced: Atoms on the left of the arrow Atoms on the right of the arrow 2 H 2 H 2 I 2 I —————————————————————————————————————————————C + S8à CS2Use the table below to show the initial numbers of reactant and product atoms: Atoms on the left of the arrow Atoms on the right of the arrow Rewrite and balance the equation: Use the table below to show that the reaction is correctly balanced: Atoms on the left of the arrow Atoms on the right of the arrow 2.
