Is this right ? I’m stuck on the Explanation part .
Alex777 [14]

Answer:

Lots of things here

Explanation:

Ammonia structure is written as NH3

carbon monoxide is CO

make bonds between O2, so there is 2 oxygen atoms per group,

anything with multiple elements bonded is a compound, thus your answer for carnon monoxide isnt correct, it should be CO for written and it is a compound. Fix your formula for ammonia and also max a bond between those two oxygens because it is O2 not O,

Your structure for SO2 is improper aswell, there are only 3 elements in this molecule, and usually the one out in front of the molecule is the central atom (except hydrogen). So it would go O-S-O for the structure, with only two bonding groups.
