Question

2g ferrous sulphate crystals are heated in a dry boiling tube. a. list any two observation. b. name the type of chemical reaction taking place . c write the chemical equation of the reaction​

Answer 1

observation

1.it losses water

2.the green colour of ferrous sulphate changes into white and then on for the heating it changes into Brown.

decomposition reaction .

2feso4=fe2o3+so2+so3

Answer 2

Answer:

1- it gives suffocating smell

2- there is a evolution of sulphur dioxide and sulphur trioxide

b feso4.7h2o---------> feso4+ 7h2o

upon further heating

feso4-------> fe2o3+so2+so3
