Calculate the enthalpy change when 4.00 mol cl2o7 is produced according to the following balanced equation: 2cl2(g) + 7o2(g) + 130kcal -> 2cl2o7(g) a. 1040 kcal b. -260 kcal c. 260 kcal d. -1040 kcal ** if you could explain it as well, that would be much appreciated if not, thats okay too its multiple choice
Answers: 1
is mentioned because it is for per mole of reaction. So for 4. moles of the product 
we need 4/2 moles of reaction to be used to calculate associated enthalphy change for the reaction.
