Answer:
See the image below
Explanation:
To draw a Lewis structure of a molecule, you place the least electronegative atom (Xe) as the central atom, with the more electronegative atoms (O) surrounding it.
Then you distribute the electrons around the atoms, giving every one an octet and placing any extra electrons on the central atom.
This procedure gives you four possible Lewis structures, so the actual structure is a resonance hybrid of them all.
Structure D has no formal charges, so it is the major contributor.
It is D. because the student is using a <span> thermometer and a rain gauge </span>
polyethylene contains HC=CH units.
mass of this is 26 gram/mol
number of such units =13500/26
There are two oxygens on the left side of the equation and three on the right
