Question

Calculate the mass of product B in a reaction where the reactant a AB decomposes completely into the product A and B . The mass of a AB is 35 gram and the mass of A is 22 gram.​

Answer 1

Answer:

Answer is 13gram

Explanation:

Since,according to law if conservation of mass - mass can neither be created nor be destroyed in a chemical reaction..

Therefore

AB= A+B

35g=22g+(MASS OF B)

35-22=MASS OF B

13 GRAM=MASS OF B

Answer 2

Answer:

Since according to law of conversion of mass, 50g of AB produces 40g of A and 10g of B, so when we heat 12.5g of Ab, we will get its 1/5

th

part as B and 4/5

th

part as A.
