" 1. 189 5. Magnesium reacts directly with nitrogen was to form magnesium nitride in exe c was found that 0.36 uted of magnesium produced 0.50 8 of magnesium nitride How many moles of nitrogen combined with 0.30 or magnesium? (b) What is the ratio of nitr o msono atoms in magnesium nitride? (c) What is the empirical formuls of magnesium nitride? 3M + M2 Mg 3N2 023 (9) No. of mol at mg 0.6 No. of mol of M₂ 24-309. n = D-18 - (1) Mg3N₂ 20.0148 m 3 = 493x10-3 roll 6. When copper(1) sulfide is partially roasted in air (reaction with O2), copper(I) sulfite is formed first. Subsequently, upon heating, the copper sulfite thermally decomposes to copper(I) oxide and sulfur dioxide. Write balanced chemical equations for these two reactions. 2 CuzS +302 2 Cu₂SO3 Cuz Soz a Cuzo + So₂ yright 2019 Pearson Education, Inc.
