Question

An element x combines with an another element y in the weight ratio of 1:3. If 10g of X is made to react with 35g of Y to form a compound, what will be the total weight of the new compound which is formed?

Answer 1

• Ratio is 1 : 3 between x and y

• So 10 g of x would react with 30 g of y

• Now due to conservation of mass we can conclude that total mass = 10 + 30 = 40

• And 5 g of y would remain unreacted

Answer 2

Answer:

35 g

Explanation:

• Ratio is 1 : 3 between x and y

• So 10 g of x would react with 30 g of y

• Now due to conservation of mass we can conclude that total mass = 10 + 30 = 40

• And 5 g of y would remain unreacted
