Question

Ba + O2 = BaO
H2O + SO2 + H2SO3
Mg + HCl MgCl2 + H2
NaNO3- NaNO2 + O2
Na + H2O + NaOH + H2
ZnS + O2 + ZnO + SO2
Ca + O2 + CaO​

Answer 1

Ответ:

Объяснение:

2Ba + O2 = 2BaO

H2O + SO2 = H2SO3

Mg + 2HCl = MgCl2 + H2↑

2NaNO3 -> 2NaNO2 + O2↑

2Na + 2H2O = 2NaOH + H2↑

2ZnS + 3O2 = 2ZnO + 2SO2

2Ca + O2 = 2CaO
