If 14.2 g of Al(NO_3)_3 is dissolved in 655g of water, what is the boiling point of the solution

100.052 degrees C

Explanation:

It has been experimentally proven that the addition of solute to water will result in boiling point elevation due to the presence of more molecules. The boiling point elevation refers to the tendency of a solvent's boiling point to increase when an impurity (a solute) is added.

The formula of boiling point elevation is

, where m is the molality defined as the number of moles of solute per kilograms of solvent and is the molal boiling point elevation constant.

Given that the molal boiling point elevation constant of water is 0.512 ,

To evaluate the boiling point of the aluminium nitrate solution,

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
