In this question, they are given that some assertions are given and reasons are given for these

answer this question. So the answer for the first sub part is assertion is false. Assertion is f

So here we see what is happening. Here it is not critical. So here it is not critical. So what i

We have given this reaction. What is happening in this reaction? MG will get oxidized and zinc w

Hey welcome to the video from the given data we can see that W is not reacting with ion nitrate

Question

ASSERTION AND REASON QUESTION: The following questions consist of two statements - Assertion (A) and Reason (R). Answer these questions selecting the appropriate option given below. a)Both A and R are true and R is the correct explanation of A b)Both A & R are true but R is not the correct explanation of A c)A is true but R is false. d) A is false but R is true 1. Assertion (A): Calcium carbonate when heated gives calcium oxide and water Reason (R): On heating calcium carbonate, decomposition reaction takes place. 2. Assertion (A): Brown fumes are produced when lead nitrate is heated. Reason (R): Nitrogen dioxide gas is produced as byproduct due to the decomposition of lead nitrate. 3. Assertion (A): White silver chloride turns grey in sunlight. Reason (R): Decomposition of silver chloride in the presence of sunlight takes place to form silver metal and chlorine gas. 4. Assertion (A): Pungent smelling gas is produced when sulfur burns in air. Reason (R): Sulfur trioxide is formed upon the reaction of sulfur with oxygen. 5. Assertion (A): In a reaction of copper with oxygen, copper serves as a reducing agent. Reason (R): The substance which gains oxygen in a chemical reaction is a reducing agent.
