Neco Model Questions Vol1 2022 Chemistry Question 9
Practice objective / multiple choice question 9 from the 2022 Neco Model Questions Vol1 Chemistry examination.
A sample of \(5.00\) g calcium carbonate (\(CaCO_3\)) is reacted with excess hydrochloric acid. The reaction is: \(CaCO_3 + 2HCl \rightarrow CaCl_2 + CO_2 + H_2O\). Only \(80\%\) of the theoretical amount of calcium chloride (\(CaCl_2\)) is obtained. The obtained \(CaCl_2\) is then reacted with excess sodium sulfate (\(Na_2SO_4\)) according to: \(CaCl_2 + Na_2SO_4 \rightarrow CaSO_4\downarrow + 2NaCl\). Calculate the mass of calcium sulfate (\(CaSO_4\)) produced (in grams).
