Let's first Find the frequency. Energy E and frequency ν are related by the Equation E = hν, where h is the constant of Planck h = 6.63 * 10^-34 J.s
By hypothesis, E = 5.09*10^19 J
E = hv so v = E/h = (5.09*10^-19) / (6.63 * 10^-34) ≈ 7.677 * 10^14 s.
Now Wavelength λ = celerity c / frequency ν, where c = 3 * 10^8 m/s
So λ = (3*10^8) / (7.677 * 10^14) ≈ 3.907 * 10^-7 m = 390.7 nm
Hope this Helps! :)
There are six common types of reactions:
1. Combination
2. Decomposition
3. Single Displacement
4. Double Displacement
5. Combustion
6. Redox
The reaction: SO₃₍g₎ + H₂O₍l₎ → H₂SO₄₍aq₎ is classified as a combination reaction. This is because for combination reactions, two (or more) reactants form a single product. On the other hand, decomposition reactions involve a single reactant breaking down into two or more simpler substances. Displacement reactions involve a more active element displacing a less active element from a compound. Meanwhile, combustion reactions involve a carbon-containing compound reacting with oxygen to form carbon dioxide and water. Redox reactions then involve exchange of electrons between species.
Answer:
we only see parts of the lit side as the moon goes around the earth
Explanation:
Unlike the sun, the moon orbits the Earth. This is the reason why we see the <em>different phases of the moon.</em> The reflection of the moon is being illuminated back to us with the help of the sun. So, as the moon circles the Earth, we only see parts of the lit side. Such changes helps us see the moon in different phases such as<em> </em>the <em>Third Quarter, Crescent, New Moon, Full Moon, etc.</em>
For example, during "Full Moon," <em>the moon's entire face is lit up by the sun</em>. Thus, we see the entire moon's lit portion.
Thus, this explains the answer.
Answer:
As the level of carbon dioxide in the blood increases, more H+ is produced and the pH decreases. This increase in carbon dioxide and subsequent decrease in pH reduce the affinity of hemoglobin for oxygen. The oxygen dissociates from the Hb molecule, shifting the oxygen dissociation curve to the right.
