Answer 2

To balance these chemical equations, you'll need to ensure that there are an equal number of each type of atom on both sides of the equation. I'll provide you with the balanced equations for each of the given reactions:

a) CaO + 2HNO3 → Ca(NO3)2 + H2O

б) 2K2SO4 + 3CaCl2 → 3CaSO4 + 4KCl

B) 3Na2S + 2CuCl2 → 6NaCl + Cu2S

в) Mg(OH)2 + H2SO3 → MgSO3 + 2H2O

г) FeO + 2HCl → FeCl2 + H2O

д) 3Ca(OH)2 + 3SO2 → 3CaSO3 + 3H2O

е) 2Cr(OH)3 + 6HBr → 2CrBr3 + 6H2O

ж) Ni(NO2)2 + 2KOH → Ni(OH)2 + 2KNO2

з) 2Na2SO3 + H2SO4 → 3Na2SO4

и) 2Fe(OH)2 + H2SO4 + 2HNO3 → 2FeSO4 + 2H2O + 2NO2

й) Ca(OH)2 + 2HBr → CaBr2 + 2H2O

к) 4Fe2O3 + 12HCl → 8FeCl3 + 6H2O

л) 2KOH + N2O5 → 2KNO3 + H2O

м) CaSO3 + 2HCl → CaCl2 + H2SO3

н) BaSO3 + H2SO4 → BaSO4 + H2O

These are the balanced chemical equations for the given reactions.
