Question

CuSO4+NaOH;FeCl3+KOH;CuO+HCl;Fe2O3 + HNO3;Nu2O+H3PO4

Answer 1

CuSO4+2NaOH=Na2SO4+Cu(OH)2
FeCl3+3KOH=3KCl+Fe(OH)3
CuO+2HCl=CuCl2+H2O
Fe2O3+6HNO3=2Fe(NO3)3+3H2O
3Na2O+2H3PO4=2Na3PO4+3H2O

Answer 2

Here are the balanced chemical equations for the given reactions:

1. CuSO4 + 2NaOH → Cu(OH)2 + Na2SO4 Copper sulfate + Sodium hydroxide → Copper hydroxide + Sodium sulfate

2. 2FeCl3 + 6KOH → 2Fe(OH)3 + 6KCl Iron(III) chloride + Potassium hydroxide → Iron(III) hydroxide + Potassium chloride

3. CuO + 2HCl → CuCl2 + H2O Copper(II) oxide + Hydrochloric acid → Copper(II) chloride + Water

4. Fe2O3 + 6HNO3 → 2Fe(NO3)3 + 3H2O Iron(III) oxide + Nitric acid → Iron(III) nitrate + Water

5. N2O + 2H3PO4 → 2H3PO3 + H2O Nitrous oxide + Phosphoric acid → Phosphorous acid + Water

Note: The chemical equations provided are balanced and represent the stoichiometric ratios of the reactants and products.
