The vapor pressure of a compound refers to the pressure generated by the vapour of a compound in equilibrium with its condensed stage. The major determinant of a compound vapour pressure is temperature. The vapour pressure of an aqueous solution of sodium chloride will be lower than that of pure water. This is because, dissolution of solute in a solvent always reduces the vapour pressure of the solution as a result of interactions between the molecule of the solute and the solvent. Thus, a pure compound will always have a higher vapour pressure than a solution.

Explanation:
Rutherford (1871–1937) was subject for an extraordinary array of discoveries in the fields of radioactivity and nuclear physics. He identified alpha and beta rays, set forth the rules of radioactive decay, and recognized alpha particles as helium nuclei.In 1911, Rutherford realized that atoms not detached, they are managed by something else, a nucleus. He noticed that the preponderance of an atom's mass is contemplated at a very tiny point in the center where the nucleus was determined. The nucleus is a positive force enclosed by electrons which are negative free flying particles.
To calculate the volume of 20.0 g of benzene, use the formula volume = mass/density. Given that the density of benzene is 0.879 g/mL, the volume is approximately 22.75 mL when you divide 20.0 g by 0.879 g/mL.
To find the volume of 20.0 g of benzene, we need to use the density of benzene because density is defined as mass per unit volume (density = mass/volume). The formula to calculate the volume from the mass and density is volume = mass/density.
In this case, we are given:
To calculate the volume, we divide the mass by the density:
Volume = Mass / Density = 20.0 g / 0.879 g/mL
We can now perform the calculation:
Volume = 20.0 g / 0.879 g/mL ≈ 22.75 mL
Therefore, the volume of 20.0 g of benzene is approximately 22.75 mL.

Answer:
Autumn is one of the four basic seasons of the year in the temperate climate zone. It is characterized by moderate air temperatures with a decreasing daily average, and relatively high annual precipitation. The climate autumn is the period of the year in which the average daily air temperature ranges around 10° C.
Astronomical fall begins at the fall equinox and lasts until the winter solstice, which roughly means in the southern hemisphere between March 23 and June 22 (sometimes these dates are a day earlier or a day later, and in a leap year they may be additionally retracted one day). During astronomical autumn, the day time of the day is shorter than the night time, and moreover, with each successive day of the day it decreases and night increases.
