Ответ:
Be(OH)2 + 2HCl → BeCl2 + 2H2O
Be(OH)2 + 2NaOH → Na2BeO2 + 2H2O
BeO + 2HCl → BeCl2 + H2O
BeO + 2NaOH → Na2BeO2 + H2O
2Cr(OH)3 + 3H2SO4 → Cr2(SO4)3 + 6H2O
Cr(OH)3 + 3KOH → K3[Cr(OH)6]
Cr2O3 + 3H2SO4 → Cr2(SO4)3 + 3H2O
Cr2O3 + 2KOH → 2KCrO2 + H2O
Sn(OH)2 + 2HNO3 + (n-2)H2O → SnO2 * nH2O + 2NO2
SnO+2KOH→K2SnO2+H2O
