To carry out the synthesis of hydrogen fluoride from hydrogen and difluorine, 1.0 mol of H, and 2.0 mol of F2, are mixed in a flask having a 3.0 L capacity. The equilibrium constant for
this synthesis reaction and at a certain temperature is equal to 115.
Calculate the concentration at equilibrium of each of the components of the reaction system.

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.  

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
