A strong electrolyte dissociates completely into ions in aqueous solution. When magnesium acetate, a strong electrolyte, is put into water the cations and anions are surrounded by water molecules and the solid dissolves.
Mg(CH3COO)2(s) --> Mg2+(aq) + 2CH3COO-(aq)
MgCrO_4_(s) ----> Mg^2+(aq) + CrO_4_^2-(aq)

Magnesium does react with water at room temperature. It does however not catch fire as such. It is a "slow" reaction and does not self-ignite. It forms Magnesium Oxide and Hydrogen when it reacts with water. Larger (not that large) quantities of Magnesium on fire will not be put out by being submerged in water. Water can however put it out if one sprays it with water at high enough force. This will cool down the metal and it will not longer be able to sustain the fire. It will burn in an atmosphere of pure nitrogen unlike almost any other fires. Easiest way to put out a Magnesium fire is to cover it with sand or salt.
Write the reaction when potassium sulfide is put into water:
You would get a very energetic (or even explosive) reaction which would produce magnesium sulphate and hydrogen gas.
put simply limescale is caused by the reversal of the reaction that takes place to make hard water that contains high levels of calcium and magnesium when the reaction is reversed this is what causes limescale. to test for hard water use a block of standard soap and if the soap makes scum the water is hard water if it creates bubbles it is soft water

Sodium bicarbonate reacts with acetic acid (found in vinegar) and presents a simple and showy demonstration of a chemical reaction. The products of the ensuing two-stage reaction are sodium acetate, water, and carbon dioxide are - NaHCO3 + CH3COOH -------→ CH3COONa + H2O + CO2(g)

Magnesium is flammable. It burns very hot and bright and cannot be put out with water or a normal fire extinguisher.
When you boil vinegar and baking soda together, it will start to evaporate. The heat at 100 degrees Celsius (212 degrees Fahrenheit) will start to evaporate nine tenths (90 percent) of the vinegar and baking soda mixture and it will form some sort of crystal called sodium acetate. If you over cooked the sodium acetate, then you will find a big yellow lump. Make sure you stir when making the sodium acetate. Now, you can make instant ice using sodium acetate. Just put cold water in the pan, then when boiled mix in the sodium acetate, and when nothing else can absorb the water, put the mixture inside a glass cup, put it in the freezer for a while, and then when you touch it, it will form ice in about five seconds. You can do more stuff with sodium acetate, that is just one of the few examples I gave you.
