Question

A teacher uses beans to model a chemical reaction. The model is shown in the diagram.

Model of a chemical reaction shown by using beans. Three beans represented as solid reacts with three beans represented as liquid produces three beans of solid and three beans of gas.

According to the law of conservation of matter, how does the combined mass of C and D compare to the combined mass of A and B?
A. The combined mass of C and D is slightly less than the combined mass of A and B.
B. The combined mass of C and D is the same as the combined mass of A and B.
C. The combined mass of C and D is slightly more than the combined mass of A and B.
D. The combined mass of C and D is very different from the combined mass of A and B.

Answer 1

Answer:B

Step-by-step explanation:

Law of conservation of mass states how many you start with is how many you end with. So you started with 6 beans (3 of each) and you end with 6 beans.
