What is a compound?

[YT2095]

get a periodic table, and count how many Different elements are in Each of those you listed.

 

if there`s more than One element involved then you can ignore it as Not the answer

 

 

btw (and this isn`t the answer) but What is: "NacI" ????

I was assuming a CAPS problem/typo; either NaCI (whatever that is) or, more likely, NaCl

[YT2095]

agreed, looking back on the OP I see HCI instead of HCl too

 

I Did wonder because I know Woelen has done Double Halogen compounds before, but NaCI (or NaClI) didn`t sit right.

I sometimes think people on these forums are from third-world countries because of their keyboard layouts. I'm not sure, but I've been thinking this for a while.
