Neco 2025 Chemistry Question 44
Practice objective / multiple choice question 44 from the 2025 Neco Chemistry examination.
Two hundred grams of calcium carbonate are reacted with excess hydrochloric acid according to \(\text{CaCO}_3 + 2\text{HCl} \rightarrow \text{CaCl}_2 + \text{CO}_2 + \text{H}_2\text{O}\). The carbon dioxide is collected over water at \(25^{\circ}\text{C}\) and a total pressure of \(750\) mmHg. The water‑vapour pressure at this temperature is \(23.8\) mmHg and the dry \(\text{CO}_2\) volume measured is \(0.450\) L. Calculate the percent yield of the reaction.
