The correct answer for this question is "<span>The mass of the products equals the mass of the reactants because the same matter is present."
All chemical reactions follow the Law of Conservation of Mass which states that mass cannot be created nor destroyed. This means that mass is constant before and after a process. If ever it seems like the mass is not the same, it is possible that the missing mass was converted to something else.</span>

Explanation:
In the given table showing the average daily calories requirement according to the weight of the adult men. Which is as follows:
weight daily intake
132 2250
154 2450
176 2650
198 2850
220 3050
242 3250
In this, the highlight weight and required calories should be taken by the man who does not perform any physical exercise but according to the question a man with 154 lb perform a moderate exercise, and according to the CDC a 154 lb men can burn anywhere between 140 and 295 calories in 30 minutes by moderate exercise for an hour.
Thus, the total calories he takes: 2700
burn by exercise: 295
should take: 2450
then = 2700 - (2450+295)
= 50 calories over the limit that will have negligible effect on the weight.
