Answer 1

Answer:

Fe + SO2 --------> Fe(SO2)

Answer 2

Dear Student,

◆ Answer with explaination -

When iron is heated with sulphur,iron sulphide is formed.

Fe + 2S --> FeS2

According to law of conservation of mass, mass of reactants will be equal to mass of products.

Mass of reactants = Mass of products

Mass of iron + mass of sulphur = Mass of sulphur dioxide

Hence, total mass of iron and sulphur is equal to the mass of iron sulphide.

Hope this helped you...
