Question

Name the gas produced when cacl2 reacts with coc H2So4

Answer 1

➠ AnSwer :-

• We will then add aqueous sulfuric acid (H2SO4) to the products of Reaction 1 to form calcium sulfate (CaSO4), water, and carbon dioxide (CO2).

➙ Carbon dioxide will evolve as a gas:-

Reaction 2: CaCO3(s) + H2SO4(aq) → CaSO4(s) + H2O(l) + CO2(g) ↑ The arrow written next to CO2 indicates that this product escapes as a gas.

Answer 2

Answer:

when cacl2 + H2so4 = caso4 + Hcl
