Scientific experiments are used to show what happens during a chemical reaction.

A chemical reaction is always written with the reactants (the things you mix together to do the reaction) on the left and the products (the stuff you get) on the right. In between is an arrow pointing right to indicate that the reactants react and become the products. Catalysts are sometimes listed above the arrow. And don't forget to balance the equation.
Yes, bubbling may be a sign for a chemical reaction.
Chemical Equation
dry, certainly not. as aqueous solution, but no evidence would show a double replacement reaction.
On heating penta hydrated copper sulphate undergoes dehydration and changes colour from blue to white that means physical change but on heating it does not show a chemical change.
It helps show you what goes on during a chemical reaction

no
colour change fizzing new substance produced
It is a chemical change because the chemical composition is changed during this reaction.
Symbols are used for the graphical representation of a chemical reaction.

Yes. This is due to the law of conservation of mass/matter.
