Answer:
Mass of product B = 15g
Explanation:
Reaction:
AB → A + B
Mass of AB = 25g
Mass of A = 10g
Unknown:
Mass of B = ?
Solution:
Based on the law of conservation of matter "matter is neither created nor destroyed but transformed from one form to another in a chemical reaction".
The amount of product = amount of reactant
Mass of AB = Mass of A + Mass of B
Now;
Mass of Product B = Mass of AB - Mass of A
Mass of product B = 25 - 10 = 15g
Mass of product B = 15g
