The radius of the football would be 748299320 times bigger than that of one atom of fluorine.
<h3>Atomic radius of fluorine</h3>
The atomic radius of a fluorine atom is 147 picometers or 147 x m.
The radius ratio of a football with 11 cm radius and that of one atom of fluorine can be calculated as:
11 x /147 x
= 748299320
Thus, the radius of the football would be 748299320 times bigger than that of one atom of fluorine.

Explanation: Temperature Affects Density
When the same amount of water is heated or cooled, its density changes. When the water is heated, it expands, increasing in volume. ... The warmer the water, the more space it takes up, and the lower its density.
Answer:
During the initial cell operation, each reaction is thermodynamically favorable, but the larger operating potential of the lithium-iodine cell indicates that its cell reaction is more thermodynamically favorable. ( B )
During the initial cell operation, the oxidation of iodine is thermodynamically favorable but the oxidation of mercury is not. ( C )
Explanation:
<u>The major Differences between The Zinc mercury cell and Lithium-iodine cell are :</u>
During the initial cell operation, each reaction is thermodynamically favorable, but the larger operating potential of the lithium-iodine cell indicates that its cell reaction is more thermodynamically favorable. and
During the initial cell operation, the oxidation of iodine is thermodynamically favorable but the oxidation of mercury is not.
Given the relationship below,
Δ G = -nFE
E = emf of cell , G = free energy.
This relationship shows that if E is positive the reaction will be thermodynamically favorable also if E is large it will increase the negativity of free energy also From the question we can see that with the reduction of mercury the value of E is more positive and this shows that Mercury is thermodynamically unfavorable
