If a propane heater burns 38.95 g c3h8, it consumes

The correct answer option is 0.883 moles

Explanation:

We are to find the number of moles that are consumed when a propane heater burns 38.95 g .

For this, we will divide the mass (38.95 g) of propane () by the molar mass which is:

C = 12.01

H = 1.01

Dividing the mass by 44.11 to get the number of moles consumed:

= 0.883 moles

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.

the answer is either b or c
