Question

Na₂S + H₂SO4 ------>​

Answer 1

Na2S + H2SO4 (разб.) → Na2SO4 + H2S↑;

Na2S + 3H2SO4 (конц.) → 2NaHSO4 + SO2↑ + S↓ + 2H2O.

Answer 2

The balanced chemical equation for the reaction between sodium sulfide (Na2S) and sulfuric acid (H2SO4) to form products would be as follows:

Na2S + H2SO4 → Na2SO4 + H2S

In this reaction, sodium sulfide reacts with sulfuric acid to produce sodium sulfate and hydrogen sulfide as the products.
