Anatural gas mixture contains 90 wt.% methane, 3 wt.% n, and 3wt.% h2s and 4wt."co. if the atomic weight of c-12, h-1, n=14,0 16, s-32, calculate - c) the specific gravity of the mixture. assume mw of air 29 d) compressibility factor (z) at 75°f and 2010 psia.

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.  

a corroding iron, if that's one of your choices
