Question

which of the reaction is not feasible ?​

Answer 1

Answer:

the first reaction is feasible. as the reaction goes like:-

Na2CO3 (aq) + SO2 (aq) → Na2SO3 (aq) + CO2 (g)

the second reaction is also feasible. as the reaction goes like:-

SiO2 + 2Na2CO3 → Na4SiO4 + 2CO2

III reaction is also possible as it goes like :-

2NaCl + F2 → 2NaF + Cl2

4th reaction is also possible as it goes like:-

SO2 + H2S = S + H2O
