i think A

Answer 5

@TheGamer - 'hydroxide' is not an element

Thechemical formula shows you the atoms present:

Na
O
H

If you don't know which elements these letters represent then look it up on the Periodic table of elements

Answer 6

Also note that all elements are represented by 1 or 2 letters for their symbol

BUT if there are 2 letters then they are always written with the first as capital letter and the second as lower-case.

SO you can see that in the above compound Na cannot be Nitrogen and something else because the a is lower case.

(there is NO element with symbol A btw)
