Combustion of the candle is a/an -
1) Exothermic reaction
2) Photochemical reaction
3) Physical change
4) Endothermic reaction

(a) Compute the Q values for these reactions.Identify
whether each reaction is exothermic or endothermic.

(1)
1

Your response differs from the correct answerby 10% to
100%. MeV

2---Select---exothermicendothermic



(2)
3

Your response differs from the correct answerby orders
of magnitude. MeV

4---Select---exothermicendothermic



(b) Which reaction results in more released energy? Why?

5


(c) Assuming the difference is primarily due to the work donebythe
electric force, calculate the distance between the twoprotonsin
helium-3.
