know the approximate percentages by volume of the four most abundant gases in dry air
know the approximate percentages by volume of the four most abundant gases in dry air
understand how to determine the percentage by volume of oxygen in air using experiments involving the reactions of metals (e.g. iron) and non-metals (e.g. phosphorus) with air
describe the combustion of elements in oxygen, including magnesium, hydrogen and sulfur
describe the formation of carbon dioxide from the thermal decomposition of metal carbonates, including copper(II) carbonate
know that carbon dioxide is a greenhouse gas and that increasing amounts in theatmosphere may contribute to climate change
practical: determine the approximate percentage by volume of oxygen in air using a metal or a non-metal
