Answer:
Mole fraction of alcohols in liquid phase 
.
Mole fraction of alcohols in vapor phase 
.
Explanation:
The total vapor pressure of the solution = p =38.6 Torr
Partial vapor pressure of the n-propyl alcohol =
Partial vapor pressure of the isopropyl alcohol =
(Raoult's Law)
is mole fraction in liquid phase.
Mole fraction of components in vapor phase 
(Dalton's law of partial pressure)
Mole fraction of alcohols in vapor phase
Answer:
6.2 moles of K2CO3 can be converted to 856.8741 grams.
<u>Answer:</u>
Earth's axis and position around the sun.
<u>Explanation:</u>
Earth's tilted axis causes the seasons to change. Throughout the year, different parts of Earth acquire the Sun's most direct rays(Or heat) because of the orbital rotation of Earth. So, when the North Pole tilts toward the Sun, it's summer inside the Northern Hemisphere. And whilst the South Pole tilts towards the Sun, it is winter within the Northern Hemisphere and vise versa.
The way I would explain it is quite difficult to understand, so this is what Google says. "The wavelength (or equivalently, frequency) of the photon is determined by the difference in energy between the two states. These emitted photons form the element's spectrum. The fact that only certain colors appear in an element's atomic emission spectrum means that only certain frequencies of light are emitted." I hope this helped.
The N2H4 bond angle will be probably 109 degrees. Since, well,<span> it has a bent </span>trigonal pyramidal<span> geometry.</span>
