Methane (CH4) is a common fuel to heat homes in the winter. What is the molar enthalpy of combustion of methane? Assume this combustion occurs entirely in the gas phase. Bond Enthalpies(in kJ mol−1):C−C: 347 C−H: 413 H−H:432 O−H: 467 C=C: 614C=O: 745O=O: 498 A)−710kJ mol−1
B)−297 kJmol−1
C)−1843 kJmol−
1D)+792 kJmol−1
E)+567 kJmol

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."

im pretty sure its b

it takes on an electronical energy
