When it dissolves it forms a carbonic acid. 1 of 7 What happens to carbon dioxide at high pressure? (water) At high pressures, more carbon dioxide dissolves in water. 2 of 7 True or false? Many metals and non-metals can't react with oxygen in the air when they are heated to produce metal oxides and non-metal oxides. FALSE! Many metals and non-metals DO react with oxygen in the air when they are heated to produce metal oxides and non-metal oxides. 3 of 7 How can oxygen be made? Oxygen can be made from hydrogen peroxide, which decomposes slowly to form water and oxygen. 4 of 7 How is carbon dioxide made? Carbon dioxide is produced whenever an acid reacts with a carbonate. 5 of 7 Calcium carbonate breaks down when heated strongly. What is this reaction called? This reaction is called thermal decomposition. 6 of 7 Name 2 other metal carbonates that decompose in the same way. sodium carbonate, copper carbonate, magnesium carbonate. 7 of 7
