Is dissolving powder into water a chemical change?
No, dissolving powder into water is a physical change, not a chemical change. The powder molecules are still the same chemical compounds as they were before dissolving, just dispersed in the water molecules.
Is dissolving NaCl in h2o a chemical change?

How could you prove to someone that the dissolving was a physical to change not a chemical change?
You can demonstrate that dissolving is a physical change by showing that the chemical composition of the substance remains the same before and after dissolving. This can be done by evaporating the solvent and obtaining the original substance in its solid form. Chemical changes involve a change in the chemical composition of the substances involved, leading to the formation of new substances, which is not the case in dissolving.
Explain why dissolving is a physical change?
