1/ When lead nitrate is heated it decomposes to form :
a. Lead oxide
b. Nitrogen dioxide
2/ thermal decomposition reaction
3/ 2Pb(NO3)2 --heat--> 2PbO + 4NO2 + O2
Hope it helps
Mark it as BRAINLIEST if you are satisfied with the answer
1. Brown fumes are emitted(NO2)
2.Lead nitrate which is white in color on heating forms lead oxide which is yellow in color.
(II) Thermal decomposition(iii)pls mark as brainliest
1.When lead reacts with nitrate radical it forms lead nitrate. ... When lead nitrate is heated, it due to thermal decomposition gives out metal oxide, oxygen and nitrogen dioxide. Lead gives out a yellow buff coloured residue lead oxide with a reddish brown gas nitrogen dioxide
2.thermal composition reaction
1st answer given in attached picture
Explanation:Hope this helps you
Emission of brown fumes
2Pb(NO3)2> 2PbO + 4No2 +O2
Pb(NO3)2 in presence of heat produces NO2+PbO+O2
I) a) whenever lead nitrate is heated a brown colour gas NO2 is produced.
b) oxygen gas is produced.
II) this type of reaction is known as decomposition reaction and also called as endothermic reaction.
III) balanced chemical equation,
2Pb(NO3)2 in presence of heat 2PbO+4NO2+O2.
this reaction is called thermal composition reaction.
• Observations when lead nitrate is heated in a test tube :
- A reddish brown gas is produced which is actually nitrogen dioxide or NO2.
- Colourless lead nitrate becomes yellowish lead oxide or PbO.
• Heating the lead nitrate is a thermal decomposition chemical reaction.
• Balanced chemical equation to represent the thermal decomposition of lead nitrate :
2Pb(NO3)2 = 2PbO + 4NO2 + O2
• The compound X is actually sodium bicarbonate or NaHCO3.
• Decomposition reaction of compound X :
2NaHCO3 = Na2CO3 + CO2 + H2O
• Besides an antacid,the sodium bicarbonate is also used for baking purposes.
(ii) Name the type of...
