13 Question p See page 421 A number of reactions can be used to generate common gases on a laboratory scale. For example, nitrogen can be produced from sodium metal and potassium nitrate as indicated by the balanced equation: 10Na(s) + 2KNO₂ (s) K₂O(s) + 5Na₂O(s) + N₂(g) A common laboratory-scale reaction can also generate oxygen gas by heating potassium chlorate, as indicated by the balanced equation: 2KCIO₂ (s) →→→ 2KC1(s) + 30₂(g) 1st attempt Part 1 See Hint What mass of potassium nitrate is needed to generate 177.0 L of gas, composed of 143.0 L of N₂ and 34.0 L of O₂ at 0.920 atm and 299 K, using these two reactions? g KNO, Part 2 What mass of potassium chlorate is needed to generate 177.0 L of gas, composed of 143.0 L of N₂ and 34.0 L of O₂ at 0.920 atm and 299 K, using these two reactions? g KCIO, See Hint
