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 
Longitudinal. (just remember that Transverse waves are perpendicular. T is like an inverted perpendicular sign)
Answer: The questions looks unclear

R belongs to group 3. K belongs to group 6 C belongs to group 1. H belongs to group 8
They are both important cell signaling molecules and both of them contain phosphate groups.
The layer of Earth that has partially melted material that moves the tectonic plates is Mantle. The correct option is C.
<h3>What are the layers of the Earth?</h3>
The Earth is divided into three layers: the crust, the mantle, and the core. This is the earth's outer layer, and it is composed primarily of solid rock, primarily basalt and granite. Oceanic crust and continental crust are the two types of crust.
The layer of Earth that has partially melted material that moves the tectonic plates is Mantle.
Thus, the correct option is C.
