Which of the following statement(s) are CORRECT ?

Answer:

Solution:

When red lead (Pb₃O₄) reacts with nitric acid (HNO₃), it forms lead nitrate, lead dioxide, and water. The chemical equation for this reaction is:

$P b_{3} O_{4} + 4 H N O_{3} \to 2 P b (N O_{3})_{2} (A) + P b O_{2} (B) + 2 H_{2} O (C)$

In this reaction, PbO₂ (B) is a characteristic chocolate-brown precipitate (residue). H₂O (C) is a stable liquid at room temperature.
