The correct Lewis structure of SO2 is the Lewis structure that shows all the 12 valence electrons in the molecule.
A Lewis structure shows the number of valence electrons on the valence shell of all the atoms in a compound. The electrons are shown as dots around the symbol of each element or a dash to indicate shared electrons in a covalent bond.
Looking at the Lewis structure of SO2 attached to this answer, we can see the twelve valence electrons in the molecule and how they are distributed around each atom as shown.

The larger the piece the longer it will take to break down. This is because it has more mass that needs to be broken down.
The number of electrons in the outermost shell of an atom determines its physical and chemical properties. All elements are most stable with 8 electrons (an octet) in their outer shell.
Hope this helps!!
Answer:
4 moles
Explanation:
A mole is equal to 6.02214076 × 1023 of any chemical unit (atoms, molecules, ions)
To find number of moles in 89 litres of water vapor use the following formula:
1 mole = 22.4 L
That is 1 L = 
mole
Volume of water vapor = 89 litres
Therefore,
Number of moles in 89 litres = 
≈ 4 moles
