Explanation: (I hope this is correct)
He conditions needed to produce lightning have been known for some time. However, exactly how lightning forms has never been verified so there is room for debate.
Leading theories focus around separation of electric charge and generation of an electric field within a thunderstorm. Recent studies also indicate that ice, hail, and semi-frozen water drops known as graupel are essential to lightning development. Storms that fail to produce large quantities of ice usually fail to produce lightning.

There are:
19.8g of nuts (90x0.22=19.8)
31.5g of granola (90x0.35=31.5)
16.2g of dried fruit (90x0.18=16.2)
22.5g of chocolate chips (90x0.25=22.5)
<span>Soap is less</span> effective in hard water<span> since it reacts to form a calcium or magnesium salt of the organic acid in the soap.</span>
The chemical with the lowest standard oxidation potential E has the greatest tendency to be reduced but hardest to oxidize. Of all the chemicals on this list, Iodine I2 has the the highest standard oxidation potential and Fluorine F2 has the lowest standard oxidation potential. Therefore the correct answer is C.F2 E=-2.87V.
