Agas has a pressure of 120 kpa, a temperature of 400 k and a volume of 50 milliliters. what volume will the gas have at a pressure of 60 kpa and a temperature of 200 kpa?

Reacting masses1 calcium carbonate breaks down on heating to produce calcium oxide and carbondioxide gas.caco3 + cao + co2a student heats 15 g of calcium carbonate strongly in a crucible.relative atomic masses (a): ca = 40, c = 12, o = 16.calculate the mass of calcium oxide produced by this reaction.(5 marks)
