Here are the balanced chemical equations for the reactions described: a) Magnesium ribbon reacts with water to form magnesium hydroxide and hydrogen gas. Mg(s) + 2H_2O(l) Mg(OH)_2(aq) + H_2(g) b) Hydrogen gas burns in the presence of oxygen (from air) to form water. This is the reaction for the pop test. 2H_2(g) + O_2(g) 2H_2O(l) c) Sulphuric acid reacts with potassium hydroxide in a neutralization reaction to form potassium sulfate (salt) and water. H_2SO_4(aq) + 2KOH(aq) K_2SO_4(aq) + 2H_2O(l) Drop the next question.
