chemical. when a reaction is undertaken that changes the structure of a substance and creates a new substance it is a chemical reaction. a gas is created during the reaction and a new chemical compound (sodium acetate) is left behind leaving neither of the previous elements present.
Physical Change. It is a chemical change if it is vinegar, but not if it is water, because there is no reaction.
Its a physical change as there is no reaction.
No, it is physical
Mixing salt and pepper is a physical change
It is a Physical change
Actually both physical and chemical changes are happening during cement mixing.

Its a physical change as there is no reaction.
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.
No, because the ingredients can still be separated, so it's a physical change. Once you bake it however, it's a chemical change.
mixing baking soda with water is a physical change b/c you don't change the chemical structure mixing baking soda with vinegar is a chemical change b/c you change the chemical structure ================= It is definitely a chemical reaction resulting in a chemical change.
physical because its a mixture and doesnt chemically combine

physical change
Chemical Change because u are baking it and mixing it and its changing size...so chemical change.
