BaCl2; Barium chloride.
Those compounds, calcium and hydrochloric acid, produce hydrogen (gas)
No, the equation for this reaction is: CuCO3(s) + H2SO4(aq) ---> CuSO4(aq) + CO2(g) + H2O(l) Therefore, the gas produced is carbon dioxide, this is produced in every reaction of a carbonate with an acid.
calcium carbonate, CaCO3
Magnesium hydrochloride
Let us see with hydrochloric acid. CaCO3 + 2HCl -> CaCl2 + CO2 + H2O The usual acid/base neutralization reaction with a boost. Produces a salt, water and as an added bonus, carbon dioxide gas.
When mixing these two reagents, a white precipitate, silver carbonate is formed.
chemical
it is a chemical change because it is no longer hydrochloric acid but a substance that has a different "ingredient" than it
Concentrated hydrochloric acid (fuming hydrochloric acid) forms acidic mists. Both the mist and the solution have a corrosive effect on human tissue, with the potential to damage respiratory organs, eyes, skin, and intestines. Upon mixing hydrochloric acid with common oxidizing chemicals, such as sodium hypochlorite (bleach, NaClO) or potassium permanganate (KMnO4), the toxic gas chlorine is produced.

I hope the answer I gave helps :).
Be careful with your terminology.Mixing aluminum and hydrochloric acid is not a chemical change.The resulting reaction, however, is a chemical change.
When barium ion is added to a hydroxide ion, the two opposite charges attract each other to form barium hydroxide Ba2+ + OH------>Ba(OH)2.
