Mercury is special because it is the only metal that is a liquid at room temperature
hope this helps!!
First you have to look at the mole ratios of the reactants and products and that ratio is 2:2:2 or you can reduce that to 1:1:1. That means an amount of peroxide will produce the same amount of oxygen gas. If there are 8 mol of peroxide will give 8 mol of oxygen gas
