Question

1. build the chemical formula for the single replacement reaction that occurs when potassium iodide and chlorine are mixed.

i need a hint
ki + cl₂ → ad + b
choices:
i₂ k k₂ kcl i cl₂i kcl₂ clik cli

Explanation:

Step1: Identify reaction type

Single replacement: more reactive halogen (Cl) replaces less reactive (I) in KI.

Step2: Determine products

Cl replaces I in KI: KCl (AD) and I₂ (B, since I is diatomic).

Step3: Match choices

AD is KCl, B is I₂.

Answer:

AD: KCl, B: I₂
