Want this question answered?
yes its a chemical change you get table salt and water out of it
chemical how do you know?
Aluminum hydroxide plus hydrochloric acid equals( produces ) aluminum chloride plus water.
Acid base reaction. HCl + NaOH >> NaCl + H2O
It is a physical change. The sodium hydroxide dissolves, but it is still sodium hydroxide.

It is a physical change. The sodium hydroxide dissolves, but it is still sodium hydroxide.
The reaction is NaOH +HCl = NaCl +H2O Both sodium hydroxide and Hydrochloric are "used up".
I think the answer you're looking for is a "Chemical Reaction". For instance, combining Hydrochloric Acid (HCl) and Sodium Hydroxide (NaOH) will cause a Chemical Reaction resulting in salt water (NaCl + H20).
Ca(OH)2 +2HCl --->2H2O +CaCl2
This is a chemical reaction.
It is a chemical change. Hint: if something is a reaction it is probably a chemical change.
Magnesium oxide does not "dissolve" in hydrochloric acid. Dissolution is a physical change. When magnesium oxide is mixed with hydrochloric acid, a chemical reaction takes place: Mg(s) + 2HCl ---> MgCl2(aq) + H2(g)
The chemical equation between calcium hydroxide and dilute hydrochloric acid is Ca(OH)2 + 2HCl → CaCl2 + 2H2O. In this reaction, calcium hydroxide reacts with hydrochloric acid to form calcium chloride and water.
