Neco Model Questions Vol1 2018 Chemistry Question 17
Practice objective / multiple choice question 17 from the 2018 Neco Model Questions Vol1 Chemistry examination.
In a two‑step process, aluminium reacts with copper(II) sulfate according to \[2\,\text{Al} + 3\,\text{CuSO}_{4} \rightarrow \text{Al}_{2}(\text{SO}_{4})_{3} + 3\,\text{Cu}\] . The copper produced then reacts with excess sulphuric acid: \[\text{Cu} + 2\,\text{H}_{2}\text{SO}_{4} \rightarrow \text{CuSO}_{4} + \text{SO}_{2} + 2\,\text{H}_{2}\text{O}\] . If 5.0 g of Al and 10.0 g of CuSO\(_4\) are mixed, what mass of \(\text{SO}_{2}\) is obtained after the second reaction is complete? (Molar masses: Al = 27.0 g mol\(^{-1}\), CuSO\(_4\) = 159.6 g mol\(^{-1}\), SO\(_2\) = 64.1 g mol\(^{-1}\)).
