If you have 0.750 moles of N2 how many liters do you have?

By definition [Avogadro Law]

1 mole of ANY gas occupies 22.4L at STP

so 0.75 mole N2 occupies 22.4 x 0.75 = 16.8L at STP

Explanation:

n has four pairs of electrons in the valence shell, electrons repel one another ,n has 7 protons in its nucleus, and since n has 7 protons, it must fill the second shell, giving it 4 pairs of electrons. the electrons form 3 bonds and 1 lone pair of electrons. each pair of electrons repels the other pairs, so they are equally far apart.

so all of the above

the correct answer is:

a. formation of precipitation
