Question

What is decomposition reaction?name the products obtained when ferrous sulphate crystals are heated ​

Answer 1

A decomposition reaction is a type of chemical reaction in which a single compound breaks down into two or more elements or new compounds. These reactions often involve an energy source such as heat, light, or electricity that breaks apart the bonds of compounds.

On heating, ferrous sulphate crystals lose water and anhydrous ferrous sulphate (FeSO4) is formed. So their colour changes from light green to white. On further heating, anhydrous ferrous sulphate decomposes to form ferric oxide (Fe2O3), sulphur dioxide (SO2) and sulphur trioxide (SO3).

Answer 2

Answer:

decomposition reaction is a reaction in which a compound splits into two or more substance is known as displacement reaction...Ask your question

When Ferrous Sulphate is heated strongly, it decomposes to form ferric oxide, sulphur dioxide and sulphur trioxide. ... This is a double decomposition reaction in which green colour of ferrous sulphate changes to brown due to the formation of ferric oxide.
