Question

A substance 'X', commonly used in baking products, reacts with dilute $\text{HCl}$ to produce a gas 'Y' which is used in one type of fire extinguisher. Name the substance 'X' and gas 'Y'. Write a balanced chemical equation for the reaction which takes place.

Accepted Answer

- Substance 'X' is **Sodium hydrogen carbonate** (or Baking soda, $	ext{NaHCO}_3$). - Gas 'Y' is **Carbon dioxide** ($	ext{CO}_2$). - **Balanced Chemical Equation:** $$	ext{NaHCO}_3(s) + 	ext{HCl}(aq) ightarrow 	ext{NaCl}(aq) + 	ext{H}_2	ext{O}(l) + 	ext{CO}_2(g)\uparrow$$
