HELP ME PLEASE A chemist combined some common industrial substances, methane and oxygen, in a closed container. Does the model above explain the chemist’s observation that the total mass of the contents in the container did not change when methane and oxygen chemically combined?

Select one:
A. No, the model is incorrect because there are not the same number of each atom on both sides of the chemical equation.
B. Yes, the model is correct because the same color are used for each element on both sides of the chemical equation.
C. Yes, the model is correct because the same types of atoms are on both sides of the chemical equation.
D. No, the model is incorrect because there are more lines holding the molecules together on the left side than the right side of the chemical equation.
