it is a chemical change because it is no longer hydrochloric acid but a substance that has a different "ingredient" than it
Mixing magnesium and the product of burning magnesium with hydrochloric acid would lead to a chemical change. The reaction between magnesium oxide (product of burning magnesium) and hydrochloric acid would produce magnesium chloride and water, showing a chemical reaction taking place due to the formation of new substances with different properties.
Mixing salt and water is a physical change, not a chemical change. The salt does not change its chemical composition when it dissolves in water, only its physical state.
Physical change as no new substance is formed and the properties have also not changed. Hope it helps!
Mixing sugar and cinnamon is a physical change, as it does not alter the chemical composition of either substance. A chemical change involves a rearrangement of atoms to form new substances with different properties.
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.
It is a chemical change because the products, H2 and HCl, are completely different from the reactants in their physical and chemical properties.
Be careful with your terminology.Mixing aluminum and hydrochloric acid is not a chemical change.The resulting reaction, however, is a chemical change.
Mixing magnesium and the product of burning magnesium with hydrochloric acid would lead to a chemical change. The reaction between magnesium oxide (product of burning magnesium) and hydrochloric acid would produce magnesium chloride and water, showing a chemical reaction taking place due to the formation of new substances with different properties.

It depends on what you are mixing it with.
it is a chemical change
physical :)

both chemical and physical
A simple mixing is a physical process.
