Question

someone please help ASAP!!
Which of the following chemical formulas shows an ionic compound?

A.
CO2

B.
N2O

C.
NaCl

D.
C6H12O6

Answer 1

We can rule out D automatically because it contains a poly atomic ion

Answer 2

okay...

Answer 3

What do you think the answer is?

Answer 4

probably b or c

Answer 5

Lets see
For B
N=nitrogen - charge=-3
O=oxygen -charge=-2
Given:N2O
It's not correct

Answer 6

The formula should have been
N2O3

Answer 7

so b and d are out... it cant be A cuz thats carbon dioxide? so c right?

Answer 8

Lets see
CO2
C=Carbon-charge=-4
O=oxygen-charge=-2
The formula is incorrect because there is no 4
it should have bee
C2O4

Answer 9

That leaves us with C
Na=sodium-charge=+1
Cl=Chlorine-charge=-1
This is correct because the ones cancel out
Therefore what is left is
NaCl
