Question

1. In a chemical equation, the mass of the reactants was 15 g, the mass of the

products was 12 g, Did this chemical reaction follow the law of conservation
of massa
a. Yes
b. No
c. You can't tell with the given information
So what is the answer

Answer 1

The answer is B as mass cannot be created or destroyed, therefore the mass must stay at 15g

Answer 2

b. No

Step-by-step explanation:

The law for the conservation of pasta was drafted in 1774 by the French chemist Antoine Laurent Lavoisier. The experimental studies carried out by Lavoisier led him to conclude that in a chemical reaction, which takes place in a closed system, the sum of the masses of the reagents is equal to the sum of the masses of the products. For this reason, we can say that the question above does not show a chemical reaction that obeys this law, since the masses of reagents and products are not the same.
