Question

BeO+KOH=
MgO+HNO3=
CaO+H2O=
CaO+HCl=
CaO+CO2=
Be(OH)2+NaOH=
Be(OH)2+HCl=
Ca(OH)2+ SO3=
Ca(OH)2+HNO3=
Ca(OH)2+CuCl2=

Answer 1

BeO+2KOH = Be(OH)2 + K2O
MgO + 2HNO3 = Mg(NO3)2 + H2O
CaO + H2O = Ca(OH)2
CaO + CO2 = CaCO3
Be(OH)2 + NaOH = не идет
Be(OH)2 + 2HCl = BeCl2 + 2H2O
Ca(OH)2 + SO3 = CaSO3 + H2O
Ca(OH)2+2HNO3= Ca(NO3)2 + 2H2O
Ca(OH)2+CuCl2= Cu(OH)2 + CaCl2
