Reactions, Word Equations The chemicals you put in to do the reaction are called the (REACTANTS/PRODUCTS) Task: Cut out the colour boxes and put them into this order You have to make sure that the reactants match the products so look at the names on the chemicals. Magnesium + Carbonate Magnesium + Chloride Calcium nitrate + Hydrogen Hydrochloric acid Calcium + Carbonate Hydrogen Nitric acid Copper + Carbonate Sodium + Sulphate Carbon dioxide + Water Sodium + Carbonate Copper + Phosphate Carbon dioxide + Water Sulphuric acid Hydrogen + Copper + Chloride Phosphoric acid Phosphoric acid Sodium + Sodium + Phosphate Nitric acid Magnesium Carbon dioxide + Water Carbon dioxide + Water Copper + Hydrochloric acid Now write a key: = REACTANTS /PRODUCTS = REACTANTS/PRODUCTS Calcium + Magnesium + nitrate Sulphuric acid Calcium Sulphate Hydrogen
