Question

1. what kind of reaction is represented by the equation?

(2\text{ki} + \text{pb}(\text{no}_3)_2
ightarrow 2\text{kno}_3 + \text{pbi}_2)

a) synthesis

b) double replacement

c) single replacement

d) combustion

Explanation:

Analyze the chemical equation

$$ 2\text{KI} + \text{Pb(NO}_3)_2 ightarrow 2\text{KNO}_3 + \text{PbI}_2 $$

Identify the reaction pattern

$$ \text{AB} + \text{CD} ightarrow \text{AD} + \text{CB} $$

Classify the reaction type

$$ \text{Double replacement} $$

Answer:

• (A) synthesis
• (B) double replacement (Correct answer)
• (C) single replacement
• (D) combustion
