Questiоn 5: Lithium аnd mаgnesium bоth reаct with nitrоgen. The chemical equation for the reaction between lithium and nitrogen is 6Li + N2 → 2Li3N a) Write the chemical equation for the reaction between magnesium and nitrogen. (2) b) The equation for the reaction between lithium nitride and water is Li3N(s) + 3H2O(l) → 3LiOH(aq) + NH3(g) bi) Would you say the product is basic or acidic and why? (2) bii) A sample of 2.1 g of lithium nitride is added to an excess of water. Calculate the amount, in moles, of Li3N in the sample of lithium nitride. (2) biii) Calculate the amount, in moles, of LiOH in the lithium hydroxide formed. (1) biv) Calculate the volume of 0.200 mol/dm3 sulfuric acid required to react fully with the amount of lithium hydroxide calculated in (b)(iii). Give an appropriate unit. The equation for the reaction is 2LiOH + H2SO4 → Li2SO4 + 2H2O (3) [10]
