く Question (1 point) See section 9.8 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)+2KNO3(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: 2KCIO3(s) 2KCI(s) + 302(g) 1st attempt Part 1 (0.5 point) See Periodic Table See Hint What mass of potassium nitrate is needed to generate 179.0 L of gas, composed of 135.0 L of N2 and 44.0 L of O2 at 0.920 atm and 291 K, using these two reactions? g KNO Part 2 (0.5 point) What mass of potassium chlorate is needed to generate 179.0 L of gas, composed of 135.0 L of N2 and 44.0 L of O2 at 0.920 atm and 291 K, using these two reactions? g KCIO See Hint
