Is mixing acid with base a chemical or physical change?
Adding a base to an acid or vice versa in changing the chemical properties of that solution. In both cases you are neuralizing the solution. There might be a physical change as well, but it would depend on what chemicals where mixing. But this reaction will definitely have a chemical change.
Is adding HCl to Mg and physical or chemical change?

Adding salt to water is not a chemical reaction, nor is it a chemical change. When salt dissolves in water, this is an example of a physical change. Although the sodium and chlorine ions separate in the water, no chemical reaction takes place.
When ice melts is it a physical change or a chemical change?
It is a physical change. There is no chemical reaction whatsoever.
Is cornflour and water a physical change?
Adding cornflour to water is a physical change. The reason this process is classified as such is that it does not change the chemical identities of the substances involved, which is the criterion for a process to be considered a chemical reaction. Technically, the cornflour would slowly hydrolyze in water, which would be a chemical reaction.
