The article states that amplitude plays a role in what happens to a sound wave. Why do you think higher amplitude waves are more often
transmitted while lower amplitude waves are reflected or absorbed?

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)
