The vinegar-baking soda reaction is a chemical change.
Physical
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.
The reaction between baking soda and vinegar is a chemical change because new substances are formed during the reaction. Carbon dioxide gas, water, and a salt are produced as a result of the reaction, demonstrating a chemical transformation.
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.
Baking is a chemical change.
