Is the Test tube sealed airtight or open air? Dissolving is a physical change.
It is a chemical change. When you add the two it forms two new things. Co2 and water. It's changing state.
When you combine them it is a chemical reaction (change) yes, but them combined in a solution is a physical change.
If baking soda reacts with vinegar, it is a chemical change.

The vinegar-baking soda reaction is a chemical change.
baking soda reacts with vinegar to produce sodium acetate and carbon dioxide
It is primarily a chemical change. However, physical changes also occur because of the chemical activity.
It will. It is the chemical compositions that react, not the physical state.
It is a chemical changes, as is any sort of reaction.
It is a chemical change. CH3COOH (vinegar) + NaHCO3 (baking soda) -> CH3COONA (sodium acetate) + H2CO3 (carbonic acid)...which then immediately dissociates to... H2CO3 -> H2O + CO2
