Completing and writing word equations Word equations are used to describe chemical reactions. Look at the word equations below. In each case complete the word equation by adding the name of the missing substance. (Explain your answers.) 1. sulfuric acid + sodium hydroxide __________________ + water I think this is the answer because 2. iron + __________________ iron chloride + copper I think this is the answer because 3. _____________ acid + magnesium carbonate magnesium chloride + water + carbon dioxide I think this is the answer because 4. zinc + oxygen __________________ I think this is the answer because 5. calcium + nitric acid __________________ + hydrogen I think this is the answer because Read the descriptions of some chemical reactions below. In each case state what type of chemical reaction it is and write a word equation for it. 6. Copper oxide reacts with sulfuric acid to make copper sulfate and water. 7. Zinc and hydrochloric acid react to make zinc chloride and hydrogen. 8. Magnesium and chlorine react to make magnesium chloride. 9. Copper and silver nitrate react to make copper nitrate and silver. 10. Copper carbonate and sulfuric acid react to make copper sulfate, carbon dioxide and water.
