Question

1 write one difference between an aqueous state and liquid state
2 what is catalytic decomposition, give example

Answer 1

1- Aqueous means that the compound, or element is in form of a solution (where solvent is water). Liquid means that the compound, or element is in itsliquid state. 1. For table salt to beaqueous you need to dissolve it water, and you can do it at room temperature (25°C).
2- Hydrogen peroxide will decomposeinto water and oxygen gas. Two molecules of hydrogen peroxide will produce two molecules of water and one molecule of oxygen. A catalyst of potassium permanganate can be used to speed up this process.
