    Complete and balance each of the reactions below:

    1. Na2O + H2O g 2 NaOH
    basic oxide of nonacidic cation gives hydroxide in water

    2. I2O5 + H2O g 2 HIO3
    acidic oxide with water gives oxoacid

    3. CO + H2O g no reaction
    non-reactive oxide (one of three listed in class)

    4. CaO + CO2 g CaCO3
    basic oxide acidic oxide

    5. FeO + SO3 g FeSO4
    basic oxide acidic oxide

    6. RuO4 + P4O10 g no reaction
    acidic oxide acidic oxide

    7. 2 CrO + TiO2 g Cr2TiO4
    basic oxide acidic oxide

    8. Fe2O3 + 6 H+ g 3 H2O + 2 Fe+3
    basic oxide of moderately acidic cation dissolves in strong acid to give water and metal ions

    9. Fe2O3 + H2O g no reaction
    basic oxide of moderately acidic cation - insoluble in water

    10. 2 BeO + SiO2 g Be2SiO4
    basic oxide acidic oxide
