10.0 grams of octane are burned in a bomb calorimeter containing 2.00 × 102 g h2o. if the water temperature increases from 25.00oc to 37.00oc, how much energy was released by the system?
ΔH=MCΔT M : the mass of water (2.00x10^2) C : water specific heat capacity (4.18 or 4.2) ΔT : tempreture change so energy (J) released into the water is = (200 x 4.18 x 12) = 10032J you can convert that to KJ : 10032 / 1000 = 10.032KJ
so the energy released by 10g of octane is 10032J or 10.032KJ
