Question

1.KOH + HNO3 =
2.Ca(NO3)2 + Na2CO3 =

3. Cu(OH)2 + H2SO4 =
4.KOH + Zn(NO3)2 =
5.Na2CO3 + CaCl2 =

Answer 1

1)HNO3 + KOH => KNO3 + H2O
H+ + NO3- => K+ + OH- => K+ + NO3- + H2O
H+ + OH- => H2O

2)Ca(NO₃)₂ + Na₂CO₃ → CaCO₃ + 2NaNO₃

3)Cu(OH)₂ + H₂SO₄ = CuSO₄ + 2H₂O.

4)Zn(NO₃)₂ + 4KOH → K₂(Zn(OH)₄) + 2KNO₃

5)CaCl₂ + Na₂CO₃ → CaCO₃ + 2NaCl
