What mass of potassium nitrate is needed to generate 231.0 L of gas, composed of 107.0 L of N2 and 124.0 L of O2 at 0.920 atm and 289 K, using these two reactions? What mass of potassium chlorate is needed to generate 231.0 L of gas, composed of 107.0 L of N2 and 124.0 L of O2 at 0.920 atm and 289 K, using these two reactions? A number of reactions can be used to generate common gases on a laboratory scale. For example, nitrogen can be produced from sodium metaland potassium nitrate as indicated by the balanced equation:10NA(s) + 2KNO,(s)→ K,0(s)+5Na,0(s) +N,(g)A common laboratory-scale reaction can also generate oxygen gas by heating potassium chlorate, as indicated by the balanced equation:2KCIO, (s)→ 2KCI (s) + 30, (g)->

What mass of potassium nitrate is needed to generate 231.0 L of gas, composed of 107.0 L of N₂ and 124.0 L of O₂at 0.920 atm and 289 K, using these two reactions?

What mass of potassium chlorate is needed to generate 231.0 L of gas, composed of 107.0 L of N₂ and 124.0 L of O₂at 0.920 atm and 289 K, using these two reactions?

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) + 2KNO,(s)
→ K,0(s)+5Na,0(s) +N,(g)
A common laboratory-scale reaction can also generate oxygen gas by heating potassium chlorate, as indicated by the balanced equation:
2KCIO, (s)
→ 2KCI (s) + 30, (g)
