What is the difference between the burning of Mg ribbon in air and Heating of Ferrous sulphate crystals? Write the reaction?

In Burning of Mg ribbionTwo element combine to form a more complex compound, therefore, the reaction is called as combination reaction.

2 Mg+O2→2 MgO


In Heating of ferrous sulphate crystal single compounds break down into simpler compounds, so it is a decomposition reaction.


2 FeSO4 (s)→Fe2 O3 (s)+SO2(g)+SO3 (g
