What changes can you observe when cemical reactions occur?
It depends on the chemical reaction. For example when you burn something it is a chemical reaction, but that is way different than if you mix baking soda and vinegar which is also a chemical reaction. It changes the matter into a different chemical matter make up of that substance.

no is not a chemical reaction
What is chemical change when dissolving?
1. Dissolving with reaction - an example is dissolving in an acid - involve a chemical change because new compounds are formed. 2. Dissolving without a reaction - for example dissolution of table salt in water - is not a chemical change; only dissociation can occur.
