Question

C'MON help a niqqa out! this the 10th time I bump this question.

Answer 1

addition of oxygen is oxidation
\[2 S O _{2}+ O _{2}\rightarrow 2~S~O _{3}\]

Answer 2

Ohh hehe that makes so much sense hehe

Answer 3

what about completing this redox: Cl2 + O2-->?? idk since they are non-metals

Answer 4

Like I'm used to seeing metals and non-metals so it's easy to look at their charges and stuff.

Answer 5

ClO?
