chemical I do believe. Here's why- the substances within the mixture will create a gas as they react. A chemical change is simply a change that results in one or more new substances.
no. it is a chemical change. When vinegar (a liquid) is poured on baking soda (a solid), it produces a change to carbon dioxide (a gas).
No, it is a chmical reaction (with physical concequences).
It is a chemical change, a reaction; sodium acetate is obtained.
It is a chemical change
If baking soda reacts with vinegar, it is a chemical change.

The vinegar-baking soda reaction is a chemical change.

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