Igcse Model Questions Vol1 2017 Chemistry Question 4
Practice objective / multiple choice question 4 from the 2017 Igcse Model Questions Vol1 Chemistry examination.
Calcium carbonate (\(\mathrm{CaCO_3}\)) weighing \(5.00\ \text{g}\) reacts with excess hydrochloric acid according to \(\mathrm{CaCO_3 + 2HCl \rightarrow CaCl_2 + CO_2 + H_2O}\). The carbon dioxide produced is collected over water at \(25^{\circ}\text{C}\) and a total pressure of \(750\ \text{mmHg}\). The volume of gas collected is \(1.20\ \text{L}\). (Water vapour pressure at \(25^{\circ}\text{C}\) is \(23.8\ \text{mmHg}\)). Calculate the percent yield of \(\mathrm{CO_2}\).
