CaO + HNO3 =
KOH + HCl =
Na2O + HSCu =
Zn + H2SO4 =
Ca + H2O =
Na2S + HBr =
KOH + CO2 =
NaOH + SO3 =
K2SO3 + CaCl2 =
Cr(NO3)2 + KOH =

Answer 1

CaO + 2 HNO3 = Ca(NO3)2 + H2O
KOH + HCl = H2O + KCl
Na2O + HSCu = CuO + HSNa2
Zn+H2SO4=H2+ZnSO4
Ca + 2 H2O = Ca(OH)2 + H2
Na2S + 2 HBr = H2S + 2 NaBr
2 KOH + CO2 = H2O + K2CO3
2 NaOH + SO3 = H2O + Na2SO4
