Hello Students are looking for Assertion and Reason Questions Class 10 Science Chapter 1 Chemicals reactions and equations, If yes here we Net Explanations have given Assertion and Reason MCQ for 10th Class Science Chapter 1.
Solved CBSE Class 10 Science Chapter 1 Assertion and Reason Questions – Chemicals reactions and equations. Here we (Net Explanations) working very hard to providing you with the Important Assertion Reason Questions for this Chapter.
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
Answer: 1. a) Both A and R are true and R is correct explanation of A
2. d) A is false but R is true
3. c) A is true but R is false
4.) C.) A is true but R is false.
5.) D.) A is false but R is true
6.) (c) A is true, but R is false..
