Answer:
a structural formula
Explanation:
A structural formula simply shows the arrangement of atoms on a compound or molecule.
They are mostly used in representing hydrocarbons.
Through a structural formula we can give name to a compound.
For example, the compound given is called Propane, an aliphatic hydrocarbon with 3-carbon atoms.
The bond relationship connecting the species are also shown in this designation.
Chromium (Cr): 2, 8, 8, 6
Copper (Cu): 2, 8, 8, 11
Chromium+2 (Cr+2): 2, 8, 8, 4 (if the ion retains a positive charge then the amount of electrons will decrease)
Copper+2 (Cu+2): 2, 8, 8, 9
Manganese+2 (Mn+2): 2, 8, 8, 5
Well cars need gas to run on if the car does not have gas it wont run and you cant get to places you need to go only if you have gas.
