Igcse Model Questions Vol1 2024 Chemistry Question 27
Practice objective / multiple choice question 27 from the 2024 Igcse Model Questions Vol1 Chemistry examination.
An alloy contains 85 % by mass of magnesium and the remainder is inert. When 12.0 g of the alloy is heated in excess oxygen, magnesium is oxidised according to \(2\mathrm{Mg} + \mathrm{O_2} \rightarrow 2\mathrm{MgO}\). (a) Calculate the theoretical mass of \(\mathrm{MgO}\) that can be formed. (b) If the actual mass of \(\mathrm{MgO}\) obtained is 9.0 g, determine the percent yield of the reaction.
