Пояснення:

Answer 2

Reaction 1: H2 + Cl2 → Н2S (сероводород)

The reaction between hydrogen gas (H2) and chlorine gas (Cl2) produces hydrogen sulfide gas (H2S) as the product. The balanced equation for this reaction is:

H2 + Cl2 → 2HCl

Reaction 2: H2 + S → HCl (хлороводород)

The reaction between hydrogen gas (H2) and sulfur (S) produces hydrogen chloride gas (HCl) as the product. The balanced equation for this reaction is:

H2 + S → H2S

Reaction 3: Н2 + О2 → Сu, вода

The reaction between hydrogen gas (H2) and oxygen gas (O2) produces copper (Cu) and water (H2O) as the products. The balanced equation for this reaction is:

2H2 + O2 → 2H2O

Reaction 4: СuO + H2 → вода

The reaction between copper(II) oxide (CuO) and hydrogen gas (H2) produces water (H2O) as the product. The balanced equation for this reaction is:

CuO + H2 → Cu + H2O
