Question

20. Briefly explain why this reaction is classified as double replacement: KBr+ AgNO3 KNO3+ AgBr

Answer 1

20).

double replacement reaction or metathesis, is a type of chemical reaction where two compounds react, and the positive ions and the negative ions of the two reactants switch places, forming two new compounds or products. Same is happening here.

24). According to le chatelier principle Forward reaction is favoured in C and D

And backward reaction favored in A and B.

According to which if reactant concentration increases and product concentration decreases than reaction will move to product side.
