This is a chemical change because a chemical reaction occurs, creating a whole new substance (carbon dioxide).

It is primarily a chemical change. However, physical changes also occur because of the chemical activity.
Mixing flour and baking soda is a physical change; the process of mixing them together does not in itself cause them to change into any other chemical. However, when the pastry is baked, then there will be chemical changes.
When you combine them it is a chemical reaction (change) yes, but them combined in a solution is a physical change.
It is a chemical change. CH3COOH (vinegar) + NaHCO3 (baking soda) -> CH3COONA (sodium acetate) + H2CO3 (carbonic acid)...which then immediately dissociates to... H2CO3 -> H2O + CO2
It is a chemical changes, as is any sort of reaction.
Baking is a chemical change.
