Answer:
0.104 m
Explanation:
Stress, 
Where F is force and A is area. Also, F=mg where m is mass and g is acceleration due to gravity

where
is the elongation and l is the original length

Making
the subject then

By substituting the given values and taking g as 9.81 then

The activation energy is lowered only
There are more collisions per second and the collisions are of greater energy
There are more collisions per second only
The activation energy is lowered
Omg I love Lewis structures!
You have to first identify the central atom. In this case the central atom is Carbon, and it's surrounded by two oxygen atoms.
Carbon has 4 valence electrons. Oxygen has 6 valence electrons. it will have two double bonds.
I'll take a pic of it.
