Question

In the decomposition of lead (II) nitrate to give lead (II) oxide, nitrogen dioxide and oxygen gas, the coefficient of nitrogen dioxide (in the balanced equation) is:
(All coefficients being natural numbers)

• A. $1$
• B. $2$
• C. $3$
• D. $4$

Answer 1

The correct option is D $4$

The balanced reaction is:
$2Pb(N{O}_3{)}_2\to 2PbO+4N{O}_2+O_2$
Here, the coefficient of nitrogen dioxide is $4$.
