If you add an aqueous solution of sodium sulfate (Na2SO4) to an aqueous solution of hydrochloric acid (HCl), there is NO REACTION. So, yes, it is a physical change because you made solutions of the two reagents, but for no other reason.
Yes
Chemical change (which results in physical change).
The melting of Sodium is a physical change.
Dissolving is a physical process.
Yes, dissolving sodium hydroxide in water is a physical change.
Physical
it is a chemical change Sodium carbonate + Copper sulfate react to make Sodium sulfate + Copper carbonate
Chemical change (which results in physical change).
It is a chemical change. An acid and a base reacting to form a new substance.
It is a chemical change because the products, H2 and HCl, are completely different from the reactants in their physical and chemical properties.
The melting of Sodium is a physical change.

Sodium is a chemical element, not a change.
Dissolving is a physical process.
Yes, dissolving sodium hydroxide in water is a physical change.
hydrochloric acid
Physical
Both reactants produce other products: carbon dioxide (gas), water and sodium chloride, while hydrochloric acid and sodium bicarbonate disappear.
