Be careful with your terminology.
Mixing aluminum and hydrochloric acid is not a chemical change.
The resulting reaction, however, is a chemical change.
This is a chemical reaction; synthesis of aluminium chloride.
Mixing lye (sodium hydroxide) and hydrochloric acid results in a chemical change, known as a neutralization reaction. This reaction produces water and salt as products, and involves the formation of new chemical bonds and the release of energy in the form of heat.
It is a chemical change because the products, H2 and HCl, are completely different from the reactants in their physical and chemical properties.
Both reactants produce other products: carbon dioxide (gas), water and sodium chloride, while hydrochloric acid and sodium bicarbonate disappear.
Yes, They react to form sodium chloride, carbon dioxide, and water.
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.
The mixing of sodium bicarbonate and hydrochloric acid is a chemical change, as it results in the formation of new substances (water, carbon dioxide, and sodium chloride) with different properties from the original reactants.
Mixing mossy zinc with dilute hydrochloric acid is a chemical change because a reaction occurs resulting in the formation of zinc chloride and hydrogen gas. This reaction is accompanied by a change in chemical composition, making it a chemical change.
It depends on what you are mixing it with.
