(d) Dinitrogen oxide​

Answer 1

Answer:

c) The brown gas formed is 'Nitrogen dioxide'.

Answer 2

(c) Nitrogen dioxide is the correct answer.

• On hearing lead nitrate, thermal decomposition reaction takes place. This leads formation of nitrogen dioxide which is released in the form of brown fumes.
• Moreover, yellow compound named lead oxide is also formed during the reaction.
• Oxygen gas is also released during the reaction.
• Lead nitrate is white in colour used in explosives, photography industry etc.
