Question

Ca+CaO+Ca(OH) 2+CaCl
Na+NaOH+Na2SO4+NaCl+NaNO3​

Answer 1

Ответ:

Ca+CaO+Ca(OH) 2+CaCl

2Ca + O2 = 2CaO

CaO + H2O = Ca(OH)2

Ca(OH)2 + 2HCI= CaCl2 + 2H2O

Na+NaOH+Na2SO4+NaCl+NaNO3

Na + 2H2O + 2NaOH + H2

CuSO4 +2NaOH → Cu(OH)2 + Na2SO4

Na2SO4 + BaCl2 → 2NaCl + BaSO4

NaCl + AgNO3 →AgCl↓ + NaNO3
