Assertion Reason Questions – Chemicals reactions and equations

 

The following questions consists of two statements- Assertion (A) and Reason(R).

Answer these questions selecting appropriate option given below:

a) Both A and R are true and R is correct explanation of A

b) Both A and R are true and R is not correct explanation of A

c) A is true but R is false

d) A is false but R is true

 

1.) Assertion (A) – White silver chloride turns grey in sunlight.

Reason (R) – Decomposition of silver chloride in presence of sunlight takes place to
form silver metal and chlorine gas.

 

2.) Assertion (A)- Calcium Carbonate when heated gives calcium oxide and water

Reason (R) – on heating CaCO3, decomposition reaction takes place.

 

3.) Assertion: Silver bromide decomposition is used in black and white photography.

Reason: Light provides energy for this exothermic reaction.

 

4.) Assertion (A): A white washed wall develops a coating of calcium carbonate after a few days.

Reason (R): Calcium oxide on the wall reacts slowly with carbon dioxide in the air.

 

5) Assertion: Rusting of Iron is endothermic in nature.

Reason: As the reaction is slow, the release of heat is barely evident.

 

6) Assertion (A): Zinc oxide can be reduced to zinc metal on heating with carbon. (CBSE Additional Practice Paper 2023 – 24)

Reason (R): Carbon is less reactive than zinc
