it desolves in the water
Any reaction occur.
Not a chemical reaction but the formation of hydrogen bromide (or hydrobromic acid, HBr) water solution.
no reaction take place between copper and water. so there is no blance equation.
chemical reaction between copper oxide and glucose
Yes, the flour holds chemical organisms that multiply and "feed" on water. The flour multiplies and has a chemical reaction.
No. It is a physical process, so it technically isn't a reaction.

This is a neutralization reaction; the products are a salt and water.
it cant decolourise
Epsom salt is a chemical compound (magnesium sulfate heptahydrate, MgSO4.7H2O) not a mixture.
The reaction is:2 Na + 2 H2O = 2 NaOH + H2
Neutralization is a chemical reaction between an acid and a base; the products are a salt and water.
This reaction is called neutralization.
