The valence electrons are shared between the atoms
Standard equation: N2(g)+3H2(g)==>2NH3(g), so through stoichiometry, (13.5 mol H2)(2 mol NH3/3 mol H2), yielding 9 moles of NH3<span />
Answer:
The two complex numbers are 
Explanation:
We have to form two complex numbers of the form

such that and d are irrational numbers and b and c are rational numbers.
We know that
are irrational numbers.
5 and 6 are rational numbers.
We put

Thus, the two complex numbers are: 
You would have to look for the mass of the sample and the volume of the sample.
