In an action movie, a hole is blown in the wall of an airplane’s passenger cabin at high altitude. Passengers are sucked out through the hole. Are they really “sucked” out? Explain what is actually going on.

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)
