How does hydrogen bonding affect water molecules

1 answer:

Since the oxygen likes to hog all the electrons, it gives the hydrogen molecules a slight positive charge and the itself a slightly negative charge.
Positive attracts negative, so there is some sort of attraction between water molecules, though a weak one.

Gold has a density of 19.32 g/mL. If its mass is 56.94 grams what is its volume? (BE SURE TO SHOW ALL THREE PARTS:

Alja [10]

Answer:

<h2>2.95 mL</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

$volume = \frac{mass}{density} \\$

From the question we have

$volume = \frac{56.94}{19.32} \\ = 2947204...$

We have the final answer as

<h3>2.95 mL</h3>

Hope this helps you

According to the molecular orbital energy-level diagram below, which one of the following statements is not correct about NO, NO

Lubov Fominskaja [6]

None of the statement is not correct about NO, NO+, and NO−.

Explanation:

Those molecules whose all subshells are completely filled are diamagnetic.

Those molecules whose any sub-shell is incomplete is termed paramagnetic.

Let us check the magnetism in all three molecules based on molecular orbital theory and Lewis structure

NO= number of electrons 11

It form N=O having configuration 1s2,2s2,2p6,3s1, it has 1 unpaired electron so it is paramagnetic.

Now NO-, number of electrons 12 having configuration 1s2,2s2,2p6,3s2, no unpaired electron hence dimagnetic.

Now NO+, number of electrons is 10 having configuration 1s2,2s2,2p6,3s2, dimagnetic

Let us calculate the bond order of NO-

N0- have 12 electrons as 5 of nitrogen, 6 of oxygen and 1 of - charge on oxygen.

So, bond order = $\frac{8-4}{2}$

= 2 double bonds

bond order of NO+, Number of electrons is 10

bond order= $\frac{8-2}{2}$

bond order = 3

bond order of NO, number of electrons 11

bond order= $\frac{8-3}{2}$

bond order=2.5

Larger the bond order shorter the bond.
