17.43. You add 8950 J of heat to 3.00 mol of iron. (a)What is the temperature increase of the iron?(b) If this same amount of heat is added to 3.00 kg of iron, what is the irons temperature increase?( take the specific heat of iron to be 1870 J/kg•K) o JDT DOLL FS FB F10 F11 Priser Insert Bas # 3 $ 4 5

what are the options.

explanation:

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
