Answer 5

Answer 6

Well look at the name:
Carbon.. 1 carbon
and Di-oxide... which should tell you have you have 2 oxygen atoms , or more specifically two \(\large O^{2-}\) oxide ions

Now Carbon can form 4 bons, (either 4+ or 4-\), so can you infer what the formula is?

Answer 7

4 bonds*

Answer 8

Co2?

Answer 9

yup perfect :)
Now you just need to see how you can write 3 of these molecules

Answer 10

how?

Answer 11

3CO2?

Answer 12

correct

Answer 13

yes :) indeed. CO2 is the whole molecule itself, so you can;t change it's molecular formula to say that you have more of them (You just add a number in front to say how many of those molecules you have)
