Question

2g of ferrous sulpate crystals are heated In a dry boling tube.
1. List any two observation
2. Name the type of chemical reaction place
3. Write the chemical equation for the reaction

Answer 1

Answer:

(i)  Two observations are :

(a) Change in state and colour.

(b) Evolution of gas.

(ii) Decomposition reaction.

(iii) 2FeSO4(s) +Heat → Fe2O3(s) + SO2(g) + SO3(g)

 

Answer 2

Following two observations are observed when crystals of ferrous sulphate are heated:

1. Change in state and color takes place.

2. A gas is evolved during this process. Since, the compound (ferrous sulphate) decomposes into two or more substances therefore, it is a decomposition reaction.

3. $\mathtt{ 2FeSo_{4} \longrightarrow Fe2O_{3} + So_{2 } + So_{3} }$
