Match the reaction on the top with the corresponding reaction on the left. *
hydrogen gas + oxygen gas → water gas 2Na(s) + 2H2O(l) → 2NaOH(aq) + H2(g) When methane burns, it reacts with oxygen to produce water and carbon dioxide water → hydrogen + oxygen magnesium + oxygen → magnesium oxide
solid sodium + liquid water → aqueous sodium hydroxide + hydrogen gas
2H2(g) + O2(g) → 2H2O(g)
methane + oxygen → carbon dioxide + water
Electrolysis breaks down water to form hydrogen and oxygen gas
A bright light is produced when magnesium reacts with the oxygen in air to form magnesium oxide
