Answering old questions.

Step-by-step explanation:

Answer 2

Hydrogen and chlorine react to form hydrochloric acid (H₂ + Cl₂ → 2HCl), mercury and oxygen produce mercuric oxide (2Hg + O₂ → 2HgO), iron reacts with sulfur to yield iron sulfide (Fe + S → FeS), and calcium with water forms calcium hydroxide and hydrogen (Ca + 2H₂O → Ca(OH)₂ + H₂).

1. Hydrogen and chlorine react to yield hydrochloric acid.

Match:
`\(H_(2) + Cl_(2) \rightarrow 2HCl\)`

2. Mercury and oxygen react to yield mercuric oxide.

Match:
`\(2Hg + O_(2) \rightarrow 2HgO\)`

3. Iron and sulfur react to yield iron sulfide.

Match:
`\(Fe + S \rightarrow FeS\)`

4. Calcium and water react to yield calcium hydroxide and hydrogen.

Match:
`\(Ca + 2H_(2)O \rightarrow Ca(OH)_(2) + H_(2)\)`

Each reaction corresponds to the given sentence.
