Answer:

1-metal + acid → salt + hydrogen gas

e.g    magnesium + dilute sulfuric acid  → magnesium sulfate + hydrogen

         Mg + H2SO4  →  MgSO4 + H2

2-metal oxide + acid  → salt + water

e.g    zinc oxide + dilute hydrochloric acid  → zinc sulfate + water

        ZnO + H2SO4  →  ZnSO4 + H2O

3-metal hydroxide + acid  → salt +water

e.g    zinc hydroxide + dilute nitric acid  → zinc nitrate + water

        Zn(OH)2 + 2HNO3  →  Zn(NO3)2 + 2H2O
