Gce Model Questions Vol1 2018 Chemistry Question 19
Practice objective / multiple choice question 19 from the 2018 Gce Model Questions Vol1 Chemistry examination.
Calcium carbonate (\( \mathrm{CaCO_3} \)) reacts with excess hydrochloric acid according to \( \mathrm{CaCO_3 + 2HCl \rightarrow CaCl_2 + CO_2 + H_2O}. \) A 5.0 g sample of \( \mathrm{CaCO_3} \) is completely reacted and the carbon dioxide produced is collected over water at 25 °C, 760 mm Hg total pressure. The vapour pressure of water at this temperature is 23.8 mm Hg and the volume of dry \( \mathrm{CO_2} \) collected is 1.20 L. Calculate the percentage yield of \( \mathrm{CO_2} \) based on the theoretical yield.
