Объяснение:

4NO2 + 2Ba(OH)2 = Ba(NO3)2 + Ba(NO2)2 + 2H2O

2H2S + O2 = 2S + 2H2O

Na2CO3 + 2HCl = 2NaCl + CO2 + H2O

PCl3 + 3H2O = H3PO3 + 3HCl

NaAlO2 + 4 HCl = AlCl3 + NaCl + 2H2O

2C2H6 + 7O2 = 4CO2 + 6H2O

CaC2 + 2 H2O = Ca(OH)2 + C2H2

2NH3 + 3Cl2 = 6 HCl + N2

6NaOH + POCl3 = Na3PO4 + 3NaCl + 3H2O
