Calorific value is the total energy released as heat when complete combustion of a substance occurs with oxygen under standard conditions. C2H4 + 3 O2 --> 2CO2 + 2H2O -1411kJ mol-1, 1 mole of C2H4 has mass = molecular mass in g = 2 x 12 + 4 x 1 = 28g, If 28 g of ethene liberates 1411kJ of heat then 70/1411 x 28g liberates 70.0kJ = 1.39g of C2H4, howdy, i'm in AP Chem too *severe fives* =) ok, merely write out the balanced chemical equation. 316.1 kcal b. The bond energies are: C - H 416 kJ/mol; C - C 356 kJ/mol; C= C 598 kJ/mol; O =O 498 kJ/mol; C = O 803 kJ/mol; H - … If 5.6 lit O2 is used at STP, in the combustion heat liberated is K.Cal. Set the perfect enthalpy (-1411.a million kJ/mol) to the equation (on the AP Chem Equations Sheet) the place the enthalpy of the reactants is subtracted via the enthalpy of the products. (b) How many grams of ethylene must burn to give 70.0 kJ of heat? heat of combustion of ch4 ,c2h4, and c2h6 are -890, -1411, -1560kj/mole which has lowest calorific - Brainly.in.
