2) Carbon Dioxide

3) When Ferrous Sulphate is heated strongly, it decomposes to form ferric oxide, sulphur dioxide and sulphur trioxide.

Heat

2FeSO4 (s)---------------->Fe2O3 (s) + SO2 (g) +SO3 (g).

4)  because heat is required to break the bonds present in the substance.

5) reddish.

Ferric means the iron(III) ion Fe+3, and ferrous means iron(II), which is Fe+2. Both of these ions react with oxygen, but ferric oxide is more common. Ferric oxide is Fe2 O3, and ferrous oxide is FeO. Ferrous oxide is reddish in color and is known as the mineral hematite.
