It is important to know if a particular molecule is composed of elements with different electronegativities as well as the structure of the particular molecule to explain the physical properties of the molecule.
1.00 mol/s of methane (CH4) is combined with 2.00 mol/s of oxygen (O2) as well as completely combusted isothermally to CO2 as well as H2O vapor at 500°C and 1 atm. Explain how much heat (in kJ/s) is necessary for this process. Explain the standard..
