Question

In a chemical reaction occurring in an open beaker, the reactants have a mass of 10. 0 g and contain 1000 J of energy. The products in the beaker contain a mass of 5. 0 g and 500 J of energy. Which best explains the difference in energy and mass as reactants are converted to products? kinetic energy closed systems law of conservation of energy electromagnetic energy.

Answer 1

C

Step-by-step explanation:

We have two laws that cannot be violated. The conservation of mass and the conservation of energy. The answer is C.
