The stuff is actually used in some hotpacks. It's exothermic.
It is exothermic. Energy is released as heat.

If the test tube containing the reactants mixture became hotter then it is exothermic, and if it became colder then it is endothermic. You must do the reaction to know which is which!
Pouring water on it because when it is heated it turns to an endothermic reaction and the hydrated part is boiled put of the compound it is then Anhydrous copper sulphate. When you add water it is hydrated again and this is an exothermic reaction. Which can get extremely hot so don't pour it on your hand and then hydrate it.
The reaction of sulfuric acid and magnesium produces hydrogen gas and magnesium sulphate. The acid attacks the metal, and the balanced equation for the reaction looks like this: Mg + H2SO4 → MgSO4 + H2 gas Sulfuric acid has 2 H+ ions and one SO4 ion. The sulphate ions react with the magnesium to produce magnesium sulphate, and H2 gas is released in the process.

If you are only dissolving something no reaction is occurring, so it is neither exo or endothermic

magnesium+copper sulphate =no reaction
Magnesium + sulphur -> magnesium sulphate

you get a precipitate.
No Reaction
Nope. There would be no reaction because magnesium is higher on the reactive series than magnesium. It would stay the same.
This is a simple displacement reaction - the more reactive magnesium displaces the less reactive copper from a solution of its salt. .... magnesium + copper sulphate ---> copper + magnesium sulphate Mg + CuSO4 ----> MgSO4 + Cu the blue colour of the copper sulphate will disappear and the silver coloured magnesium will be replaced by brown-red copper metal. Hope this helps. :)
