Write out and balance the following chemicalequations.
1. Sodium metal reacts violently with water to produce sodium hydroxide and
hydrogen gas.
2Na + 2H2O → 2NaOH + H2
2. Calcium oxide combines with water to produce calcium hydroxide.
CaO + H2O → Ca(OH)2
3. Hydrogen Peroxide (H2O2) decomposes to form water and oxygen gas.
H2O2 → 2H2O + O2
4. Copper(II) sulfate and aluminum react to form aluminum sulfate and copper.
3CuSO4 + 2Al → Al2(SO4)3 + 3Cu
