Question

Write the decomposition reactions of lead nitrate, ferrous sulphate And calcium carbonate​

Answer 1

The decomposition reactions of the given chemical compounds, are as follows -

• Decomposition reaction of lead nitrate :

2Pb(NO₃)₂ ---Δ----> 2PbO + 4NO₂ + O₂

• Decomposition reaction of ferrous sulphate :

2FeSO₄ ---∆----> Fe₂O₃ + SO₂ + SO₃

• Decomposition reaction of calcium carbonate :

CaCO₃ ----∆----> CaO + CO₂

• In the above mentioned reaction "∆" indicates the application of heat.
• Definition of Decomposition : Decomposition is a type of chemical reaction where a single reactant breaks down into multiple products. (usually, energy input is necessary in these chemical reactions.)
