The combustion reaction for methane is shown below:
CH4 (g) + 2O2 (g) → CO2 (g) + 2H20 (g) + energy
If 64.0 g of methane is reacted with excess oxygen gas,
what is the pressure exerted by water vapor assuming the
reaction went to completion in a 24.0 L engine at 515 K?
atm

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
