Answer:
Rareness, the others describe what the gold is and its properties.
V= 50. L n=45 mol T= 200°C = 473k P=?
CP)X 50.L)= (45 mol)(0.0821 light_kimol)(473k)
P = 30am or 4000 kPa
Formula= P4O6
You are going to want to flip the elements subscripts with one another.
P6O4
P will just stay as phosphorus, but since oxygen has 4 atoms, itbwill become tetroxide
Genetic: an organism uses energy for cellular respiration, and has all the genes necessary to make the proteins to accomplish it.
The mole fraction of pentane in the vapor is 0.291
Vapour pressure rises with temperature and is a measurement of a substance's propensity to transform into a gaseous or vapour state. The boiling point of a liquid is the temperature at which the pressure exerted by its surroundings equals the vapour pressure present at the liquid's surface.
The number of moles of a particular component in the solution divided by the overall number of moles in the sample solution is known as the mole fraction.
Using the formula for vapour pressure,
vapour pressure =

°
× 
vapour pressure = 151 × 

+ 425 × 
240 = 151 - 151
+ 425
240 - 151 = - 151
+ 425 
89 = 274 
= 
0.291 = 
Therefore, the mole fraction of pentane in the vapor is 0.291
