Neco Model Questions Vol1 2019 Chemistry Question 44
Practice objective / multiple choice question 44 from the 2019 Neco Model Questions Vol1 Chemistry examination.
When potassium permanganate oxidises hydrogen peroxide in acidic medium, the balanced equation is \(2\,\mathrm{KMnO_4}+5\,\mathrm{H_2O_2}+3\,\mathrm{H_2SO_4}\rightarrow \mathrm{K_2SO_4}+2\,\mathrm{MnSO_4}+5\,\mathrm{O_2}+8\,\mathrm{H_2O}\). If 0.030 mol of KMnO₄ reacts completely with excess H₂O₂ and H₂SO₄, calculate (a) the volume of O₂ gas produced at STP, and (b) the mass of MnSO₄ formed.
