According to the molecular orbital (mo) treatment of the no molecule, what are the bond order and the number of unpaired electro

mojhsa [17]

Attached is the MOT of NO molecule.

1. Bond order is calculated is $\frac{\text{number of e- in bonding orbital - number of e- in antibonding molecular orbital }}{2}$

In present case, number of e- in bonding orbital = 6
number of e- in anti-bonding orbital = 1
∴ Bond-order = $\frac{\text{6-1 }}{2}$ = 2.5

2. From the attached figure, it can be seen that NO has one unpaired electron in π* orbital.

A 50.6 grams sample of magnesium hydroxide (Mg(OH)2) is reacted with 45.0 grams of hydrochloric acid (HCl). What is the theoreti

zysi [14]

<span> Mg(OH)2(s) + 2HCl(aq) yield MgCl2(aq) + 2H2O(l)

grams HCl required = (50.6 grams Mg(OH)2) * (1 mol Mg(OH)2 / 58.3197 grams Mg(OH)2) * (2 mol HCl / 1 mol Mg(OH)2) * (36.453 grams HCl / 1 mol HCl) = 63.26 grams HCl required

Since there are only 45.0 grams HCl, then HCl is the limiting reactant.

theoretical yield MgCl2 = (45.0 grams HCl) * (1 mol HCl / 36.453 grams HCl) * (1 mol MgCl2 / 2 mol HCl) * (95.211 grams MgCl2 / 1 mol MgCl2) = 58.6 grams MgCl2 </span>
