Consider the reaction 2 NaN → 2 Na + 3N2, which is the first reaction that occurs when an air bag expands in a car undergoing a collision. This reaction happens very quickly, as you might suspect

A graph showing the amount of nitrogen gas (N2) could be best described as which sentence?

The graph line's general trend is absolutely horizontal.

The graph line's general trend is decreasing from left to right
right

The graph line's general trend is nearly horizontal.

The graph line's general trend is increasing from left to right from left to right

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.
