Question

Составьте ривнняння реакции HCL+Ca= HCL+ZnO= HCL+Cr(OH)3= HCL+Na2S= осуществить ривння реакции HCl-CuCl2-BaCl2-AlCl-AgCl

Answer 1

2HCl + Ca = CaCl2 + H2↑
2HCL + ZnO = ZnCl2 + H2O
3HCL + Cr(OH)3 = CrCl3 + 3H2O
2HCL + Na2S = 2NaCl + H2S↑
Цепочка:
1) 2HCl + CuO = CuCl2 + H2O
2) CuCl2 + Ba(OH)2 = Cu(OH)2↓ + BaCl2 
3) 3BaCl2 + Al2(SO4)3 = 3BaSO4↓ + 2AlCl3
4) AlCl3 + 3AgNO3 = AgCl↓ + Al(NO3)3

Answer 2

Equation for the Reaction of HCl with Ca:

The equation for the reaction of hydrochloric acid (HCl) with calcium (Ca) is as follows:

2HCl + Ca → CaCl2 + H2 [[1]]

Equation for the Reaction of HCl with ZnO:

The equation for the reaction of hydrochloric acid (HCl) with zinc oxide (ZnO) is as follows:

2HCl + ZnO → ZnCl2 + H2O [[2]]

Equation for the Reaction of HCl with Cr(OH)3:

The equation for the reaction of hydrochloric acid (HCl) with chromium(III) hydroxide (Cr(OH)3) is as follows:

3HCl + Cr(OH)3 → CrCl3 + 3H2O [[3]]

Equation for the Reaction of HCl with Na2S:

The equation for the reaction of hydrochloric acid (HCl) with sodium sulfide (Na2S) is as follows:

2HCl + Na2S → 2NaCl + H2S [[4]]

Equation for the Reaction of HCl with CuCl2, BaCl2, AlCl, and AgCl:

To balance the equation for the reaction of hydrochloric acid (HCl) with copper(II) chloride (CuCl2), barium chloride (BaCl2), aluminum chloride (AlCl), and silver chloride (AgCl), we need more information about the reaction conditions and the stoichiometry of the reactants.

Please provide additional details or specify the stoichiometry of the reactants so that we can balance the equation accurately.
