yes it as it forms a new substance
it is a chemical change Sodium carbonate + Copper sulfate react to make Sodium sulfate + Copper carbonate
It is a physical change because it has only changed state.
Copper sulfate is a substance, not a change. It can undergo physical and chemical changes.
Yes. The magnesium metal replaces the copper in the copper sulfate. This is a single replacement or single displacement reaction.
Yes, the zinc reacts with th sulfuric acid to produce zinc sulfate and hydrogen gas.

Sodium carbonate is a compound. Until you react it with something, it cant have or be a chemical change.
It is a physical change because it has only changed state.
It is not.
No, crushing sodium carbonate does not produce a new chemical substance. Thus, crushing is an example of a physical change.
Macaroni is a mixture not a change.
No, dissolving is a physical change
Chemical change (which results in physical change).
