Question

when u you heat 2g of ferrous crystals in a boiling tube. describe
i) the colour change you observed
ii) characteristics
iii) type of reaction
iv) balanced chemical equation

Answer 1

Answer:

when you heat 2g of ferrous crystals in a boiling tube. describe

(i)Colour changes from light green to white,On further heating, the white substance changes to dark brown solid.

(ii)On heating it looses water.

(iii)chemical reaction.

(iv)2FeSo4-> Fe2O3+So2+SO3

Explanation:

(i)On heating it looses water molecules and becomes anhydrous ferrous sulphate.

(ii) 1 Ferrous sulphate crystals contains 2 water moelcules. On heating it looses water molecules and becomes anhydrous ferrous sulphate.

(iii)chemical reaction because they are initial product and final product are different.

(iv) The reaction is a bit complicated. therefore just read it twice.
