Gce Model Questions Vol1 2017 Chemistry Question 16
Practice objective / multiple choice question 16 from the 2017 Gce Model Questions Vol1 Chemistry examination.
A sample containing 10.0 g of aluminium metal is mixed with 20.0 g of copper(II) chloride solution. During the reaction, 10 % of the aluminium is consumed by a side‑reaction with water to form aluminium hydroxide and does not participate in the main displacement reaction: (2\,\text{Al} + 3\,\text{CuCl}_2 \rightarrow 2\,\text{AlCl}_3 + 3\,\text{Cu}\). The main reaction proceeds with an 85 % isolated yield of copper. Calculate the mass of copper actually obtained (in grams, to three significant figures).
