Question

single compound on heating produces three products out of which one is brown in colour​

Answer 1

Answer:

lead nitrate on heating gives nitrogen brown in colour, oxygen and lead oxide

(PLEASE MARK BRAINLIEST)

Answer 2

Answer :

• Compound is = Lead nitrate [Pb(NO₃)₂]

Explanation:

• When lead nitrate powder is heated, it decomposes into 3 products-Lead oxide, nitrogen dioxide & oxygen.

• Amongst this three products, nitrogen dioxide is brown in colour and is emitted out as brown fumes.

• Reaction is as follows:-

$\rm{\underset{\text{Lead nitrate}}{Pb(NO_3)_2(s)}\xrightarrow{\text{Heat}}\underset{\text{Lead oxide}}{2PbO(s)}+\underset{\text{Nitrogen dioxide}}{4NO_2(g)}+\underset{\text{Oxygen}}{O_2(g)}}$

Additional Information :

Decomposition reaction:-

• A reaction in which a single reactant splits/breaks down into a number of simpler products which can be either a compound or an element is defined as a decomposition reaction.

Examples of decomposition reactions:

• $\rm{2FeSO_4(s)\xrightarrow{\text{Heat}}Fe_2O_3(s)+SO_2(g)+SO_3(g)}$

• $\rm{CaCO_3(s)\xrightarrow{\text{Heat}}CaO(s)+CO_2(g)}$
