The orientation in space of an atomic orbital is associated with

The magnetic quantum number is one of the four quantum numbers that characterize the quantum state of an electron bound from an atom.

This number determines the spatial orientation of the orbital and its name is due to the fact that this spatial orientation is normally defined in relation to an external magnetic field.

Therefore:

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
