Question

Ba + HCl= Al2O3+HCl= CaCO3 +HCl= H2SiO3 = Cu(OH)2+ HCl= help

Answer 1

Ответ:

Объяснение:

Ba + 2HCl = BaCl2 + H2

Al2O3 + 6HCl = 2AlCl3 + 3H2O

CaCO3 + 2HCl = CaCl2 + CO2 + H2O

H2SiO3 -> SiO2 + H2O

Cu(OH)2 + 2HCl = CuCl2 + 2H2O

Answer 2

It looks like you've provided a list of chemical reactions involving various compounds and reagents. I'll help you balance the chemical equations and provide a brief explanation of each reaction:

1. Ba + HCl (Barium + Hydrochloric Acid) This reaction doesn't actually occur as written. Barium (Ba) is a metal and would not readily react with hydrochloric acid (HCl) to form a simple binary compound. If you want a reaction involving barium, please provide more details.

2. Al2O3 + HCl (Aluminum Oxide + Hydrochloric Acid) Al2O3 + 6HCl → 2AlCl3 + 3H2O This is a balanced equation for the reaction between aluminum oxide and hydrochloric acid. Aluminum oxide reacts with hydrochloric acid to produce aluminum chloride and water.

3. CaCO3 + HCl (Calcium Carbonate + Hydrochloric Acid) CaCO3 + 2HCl → CaCl2 + CO2 + H2O This equation is balanced. Calcium carbonate reacts with hydrochloric acid to form calcium chloride, carbon dioxide, and water.

4. H2SiO3 (Dihydrogensilicate) H2SiO3 isn't a commonly recognized compound. If you're referring to silicic acid, the balanced equation for its reaction with an appropriate reagent could be provided. Please clarify.

5. Cu(OH)2 + HCl (Copper(II) Hydroxide + Hydrochloric Acid) Cu(OH)2 + 2HCl → CuCl2 + 2H2O This balanced equation represents the reaction between copper(II) hydroxide and hydrochloric acid. Copper(II) hydroxide reacts with hydrochloric acid to form copper(II) chloride and water.
