Science — AI-generated practice question

Bleaching powder is produced by passing chlorine gas over dry slaked lime [Ca(OH)₂].

$$\text{Ca(OH)}_2 + \text{Cl}_2 \rightarrow \text{CaOCl}_2 + \text{H}_2\text{O}$$

Slaked lime reacts with chlorine to form calcium oxychloride (CaOCl₂), known as bleaching powder, and water.

• The examiner expects two things: the process (chlorine passed over dry slaked lime) and the balanced chemical equation — one mark each.
• Write the full names of reactants and products alongside the formula.
• "Dry" slaked lime is important — mention it to show accuracy.
• The chemical name of bleaching powder (calcium oxychloride) is a bonus detail that strengthens the answer.
