Potassium chlorate decomposes when heated to produce potassium chloride and oxygen gas: 2 KClO3 (s) à 2 KCl (s) + 3 O2 (g) (a) If a test tube holding 87 g KClO3 is heated and the reaction goes to completion, calculate the volume of O2 gas that will be obtained if it is collected at a pressure of 1 atm and temperature of 27 °C. (Assume ideal gas behavior.)
