Question

Why does magnesium oxide have a higher boiling point than sodium chloride?

Answer 1

@zaynab123

Answer 2

This is because its Mg2+ and O2- ions have a greater number of charges, so they form stronger ionic bonds than the Na+ and Cl- ions in sodium chloride. Because magnesium oxide stays solid at such high temperatures, it remains non-conductive.

Answer 3

try answering yourself not google

Answer 6

yep that's the answer

Answer 7

please explain your answer

Answer 8

how would you out in your own words

Answer 10

Did u understand what the answer is saying ? @13ziar

Answer 11

kind of
but i need to shorten it

Answer 12

Okai why don't you shorten it a little bit I'll see if you get it right?

Answer 13

magnesium oxide have two bonds but sodium chloride has one bond inbetween

Answer 14

them

Answer 15

You can't particularly talk about the no. of bonds here, it's the charge separation .

Answer 16

could you please write the answer please

Answer 17

Write like this maybe ?
The charge separation in MgO is higher than that of NaCl. When charge separation increases the ions will be more strongly attracted to each other and as a result it needs a high amount of energy to break them thus increasing the boiling point.

Answer 18

break them as in the bond between the ions :)

Answer 19

what do you mean by charge separation

Answer 20

Charge separation is what they have talked in the previous answer !

Answer 21

well then what do they mean by it?

Answer 22

Charge separation is referred to as static electricity building of space between particles of opposite charges.

Answer 23

oh ok thnx

Answer 24

Take MgO
Mg ion has a charge +2
and O^2- has a charge of -2
So the charge separation is the static electricity +2/-2

Answer 25

no problem love :) @13ziar
