Answer 2

Matching Substances with Reagents

1) AlCl3 2) S 3) ZnO 4) Ag(NO3)2

a) H2SO4 (конц.), O2 b) HCl, Na2O c) AgNO3, NaOH d) HCl, Cu

Let's match the substances with the reagents:

1) AlCl3 - c) AgNO3, NaOH - AlCl3 reacts with NaOH to form a gelatinous white precipitate of Al(OH)3.

2) S - a) H2SO4 (конц.), O2 - Sulfur (S) reacts with concentrated sulfuric acid (H2SO4) and oxygen (O2) to form sulfur dioxide (SO2).

3) ZnO - b) HCl, Na2O - Zinc oxide (ZnO) reacts with hydrochloric acid (HCl) to form zinc chloride and water.

4) Ag(NO3)2 - d) HCl, Cu - Silver nitrate (AgNO3) reacts with hydrochloric acid (HCl) to form silver chloride and nitric acid. It also reacts with copper (Cu) to form copper nitrate and silver.

These are the corresponding reagents for the given substances.
