100 points plz with this science worksheet plz answer all of the ’m desperate

1. If the outer shell is filled, the atom isstable. Atoms with unfilled outer shells are unstable, and will usually form chemical bonds with other atoms to achieve stability. 
5. molecular formula. : a chemical formula that gives the total number of atoms of each element in each molecule of a substance — compare structural formula
The structural formula of a chemical compound is a graphic representation of the molecular structure, showing how the atoms are arranged. 

6. most likely hydrogen bonds because of the weak attraction it may have for one another

7.  search up how to draw it. Looking at Octane, you can see 18 hydrogen atoms covalently bonded to carbon atoms, so Octane is organic
8: carbon is the backbone for organic molecules because every organic molecule must contain carbon to be one. without it, it'd be considered as inorganic.

that's the best I can do

He should put sand around the spill in order to contain it so that it won't spread

Where is the data? ? and graph
