Calculate the hight of a column of liquid glycerol in meters required to exert the same pressure as 3.02 m if CCl4?

Approximately .

Explanation:

Look up the density of carbon tetrachloride, , and glycerol:

Let denote the gravitational field strength. (Typically near the surface of the earth.) For a column of liquid with a height of , if the density of the liquid is , the pressure at the bottom of the column would be:

.

The pressure at the bottom of this carbon tetrachloride column would be:

.

Rearrange the equation for :

.

Apply this equation to calculate the height of the liquid glycerol column:

.

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.
