Hello everyone today. We have the following problem. Suppose the suppose that a reaction occurs for the mixture of substances in the illustration below, choose the product mixture illustration for the reaction that obeys the law of conservation of mass. And so this essentially just states this law states that the mass or the concentration of our reactant should equal the mass or concentration of our products. So in our initial reaction here we see that we have red and we have blue balls or spheres. And so we see that we have eight red spheres and seven blue spheres. So essentially we just need to find whichever diagram has that. So for the first one we see that we have both red and blue. However, we see that there are seven red and seven blue for B. We see that we have 10 red and only five blue for C. We see that we have eight Red and seven blue and for D. We see That we have eight red and eight blue. And so our answer is going to be answer choice c. Reason being the number of red spheres remain the same. And so did the number of blue spheres. And so that's why sees our answer overall. I hope this helped. And until next time
