Energy from the sun that is neither reflected nor absorbed by the atmosphere passes through the atmosphere to the surface. The ozone layer absorbes most of the ultraviolet radiation, water vapor, and carbon dioxide absorbs infared radiation, clouds, dust, and other gases also absorb energy.
You can determine this by counting the number of electrons on the last orbital. If the number of electrons on the last orbital (valence electrons) is 8 then it satisfies the octet rule because the compound has mirrored the look of a noble gass or “neutral” charge.
Answer:
26.8224 Meters per Second.
Explanation:
As the given chemical reaction equation is as follows.
Also, it is given that for 2 moles the energy required is 130 kcal. This means that energy required for 1 mole is calculated as follows.
1 mole = 
= 65 kcal
Hence, energy required for 7 moles will be calculated as follows.
Energy required = 
= 455 kcal
Thus, we can conclude that energy required to produce 7.00 mol 
on the basis of given reaction is 455 kcal.
Answer:
The final temperature of the setup = 36.6°C
Explanation:
Let the final temperature of the setup be T
Heat lost by the copper tubing = Heat gained by water and the vessel
Heat lost by the copper tubing = mC ΔT = 455 × 0.387 × (89.5 - T) = (15759.61 - 176.1T) J
Heat gained by water = mC ΔT = 159 × 4.186 × (T - 22.8) = (665.6T - 15175.1) J
Heat gained by vessel = c ΔT = 10 × (T - 22.8) = (10T - 228) J
Heat lost by the copper tubing = Heat gained by water and the vessel
(15759.61 - 176.1T) = (665.6T - 15175.1) + (10T - 228)
851.7 T = 31162.71
T = 36.6°C
