Question

When one mole of lead nitrate is heated then:
(A) 2 moles of NO2 gas are produced.
(B) 1 moles of O2 gasisproduced
(C) both (A) and (B)
(D) 4 moles of NO2 gas are produced  ​

Answer 1

Answer: C) Both (A) and (B)...

Explanation: 2Pb(NO3)2 (s) -------≥ 2PbO (s)  +   4NO2 (g)   +  O2(g)

                      Lead Nitrate         Lead Oxide     Nitrogen      Oxygen

                                                                          Dioxide

From the Equation, it's clear that 2 Moles of NO2 gas and 1 Mole of O2 gas is produced...

I hope that the answer was up to ur satisfaction..

Answer 2

Answer:

When one mole of lead nitrate is heated then 2 moles of NO₂ gas is produced.

Therefore, the option (A) is correct.

Explanation:

The balanced chemical reaction:-

$2Pb(NO_{3})_{2}\;(s)$   $\longrightarrow$   $2PbO \; (s)$  $+ \; \; 4NO_{2}\; (g) \; \; +\; \; O_{2}\; (g)$

From the above chemical reaction we can say that, on heating of lead nitrate. We will get lead oxide (PbO), nitrogen dioxide gas and oxygen gas.

• Two moles of lead nitrate produces 4 moles of NO₂

        One mole of  lead nitrate produces 2 moles of NO₂

• Two moles of lead nitrate produces 1 moles of O₂ gas

        One mole of lead nitrate produces 0.5mole of O₂

Therefore, heating of 1 mole of Pb(NO₃)₂ will produce of 2 moles of  NO₂ gas.
