Question

By touching the side of a beaker, a student concludes that an exothermic change is taking place inside it. Write 2 - 3 sentences explaining how the student came to that conclusion and comparing the energy of the products of an exothermic reaction with the energy of the reactants.

Answer 1

hint - an exothermic energy gives off heat so will the beaker feel hot/cold?

Answer 2

cold

Answer 3

hot?

Answer 4

good, the beaker should be warm

now, as for the second part of the question, for an exothermic reaction which has more energy, the products or reactants?

Answer 5

The student came to that conclusion and comparing the energy of the products of an exothermic reaction with the energy of the reactants by realizing that an exothermic reaction gives off heat and the beaker would be warm. For an exothermic reaction the products have more energy

Answer 6

reactants have more energy but otherwise good
