Pls help ASAP. Pls circle the final answer.
Calculate the heat of reaction AH for the following reaction: CH4(g) + 202(g) →CO2(g) + 2H2O(g) You can find a table of bond energies by using the Data button on the ALEKS toolbar. Round your answer to the nearest kJ/mol. mol G
Question 11 X Incorrect. Isooctane, C3H18, is the basis of the octane rating system for gasoline because it burns smoothly, with minimal engine knocking. Pure isooctane is assigned a value of 100. Octane ratings are assigned to gasoline mixtures based on their ability to prevent knocking relative to isooctane. Estimate the energy released during the combustion of 1.00 mol of pure isooctane. Please note the combustion is exothermic process and the released energy is positive for the surroundings. -285.8 kJ
A scientist measures the standard enthalpy change for this reaction to be 296.0 kJ/mol: H₂S(g) + 2 H₂O(l) 3H₂(g) + SO₂(g) Based on this value and the standard formation enthalpies for the other substances, the standard formation enthalpy of H₂S(g) is kJ/mol.
