Unformatted text preview: the air into the collecting tube; gas is flammable Word Equations Part A A1: Magnesium plus oxygen yields ? A2: A1 product plus water yields ? Word Equations Part B B1: Copper (II) Sulfate Pentahydrate is heated to yield ? B2 Anhydrous Copper (II) Sulfate plus water yields ? Word Equations Part C C1 Iron plus Copper (II) Sulfate yields ? C2 Copper plus Silver Nitrate yields ? C3 Magnesium plus Hydrochloric Acid yields ? Instructions Complete the word equations by predicting the products, use the information you gathered by observation to help in the predictions Be sure to include the state of the substance for the reactants and products Classify the reaction The End Complete the equations for the reactions Then you may go finish Part D of the lab instructions. You will need the solubility rules....
