I think it’s B 5.54 x 10^2g
Answer:
36.63 Torr
Explanation:
You need to use two expressions, one for pressure and the other with the relation of density and height of the column.
For the pressure:
P = h * d * g (1)
h is height.
d density
g gravity
The second expression put a relation between the densities and height of the column so:
d1/d2 = h1/h2 (2)
let 1 be the phthalate, and 2 the mercury.
Let's calculate first the relation of density:
d1/d2 = 13.53 / 1.046 = 12.93
Now with the first expression, we can calculate the pressure so:
P = hdg
We have two compounds so,
h1d1g = h2d2g ---> gravity cancels out
From here, we can solve for h2:
h2 = h1*(d1/d2)
replacing:
h2 = 459 / 12.53
h2 = 36.63 mm
1 mmHg is 1 torr, therefore the pressure of the gas in Torr would be 36.63 Torr
Prochirality is an important concept in biological chemistry because enzymes can distinguish between the two ‘identical’ groups bound to a prochiral carbon center due to the fact that they occupy different regions in three-dimensional space.
Answer:
It is higher.
Explanation:
The amplitude of a wave that carries more energy is usually higher.
The energy carried by a wave is related to the amplitude in such a manner that it is proportional to the square amplitude.
Amplitude is the maximum vertical displacement of a wave moving along its path.
- Energy of wave and its amplitude are directly proportional to one another.
- If the energy of wave is doubled, the amplitude is quadrupled.
- So, the higher the energy of a wave, the more its amplitude.
