If a human produces 20.5 moles of CO2 per day. How many molecules of sugar will be needed to
produce this amount?

The reaction will shift to the right

So the main goal for the elements is stability which is a complete/full valence shell and typically the magic number for a stable element is 8 valence electron but not always. so elements to the left of the periodic table tend to be way less stable then those on the right, so the elements on the left are much more reactive.

Good job high
