✳ A substance ‘X’ used as an antacid reacts with hydrochloric acid to produce a gas ‘Y’ which is used in fire extinguishers.

(a) Name the substance ‘X’ and ‘Y’.

(b) Write a balanced equation of the reaction of ‘X’ with hydrochloric acid.

⚾Answer⚾

{a}The substance ‘X’ is baking soda or sodium hydrogen carbonate and ‘Y’ is CO2 respectively.

{b}The balanced equation of this reaction between X and hydrochloric acid is

NaHCO3+ HCI = NaCl + H20 + CO2.

a) X → Sodium hydrogen carbonate or baking soda.

y → CO2

(b) NaHCO3 + HCI → NaCI + H2O + CO2↑
