Assume that air consists of n2 molecules with a collision diameter of 395 pm. calculate (i) the relative mean speed of the molecules, (ii) the mean free path, and (iii) the collision frequency in air at 1.00 atm and 25 0c. repeat the calculations at p = 0.0500 atm and 25 0c. repeat the calculations at p = 1.00 atm and 45 0c.

beta decay is the answer

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.  

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year
