13 Question .s) 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: 2KCIO, (s). 2KC1(s)+30₂(g) Part 2 Feedback What mass of potassium nitrate is needed to generate 189.0 L of gas, composed of 103.0 L of N₂ and 86.0 L of O₂ at 0.920 atm and 293 K, using these two reactions? 800 138 g KNO, Jul See Periodic Table Feedback What mass of potassium chlorate is needed to generate 189.0 L of gas, composed of 103.0 L of N₂ and 86.0 L of O₂ at 0.920 atm and 293 K, using these two reactions? g KCIO,
