Question

S + O2 ----> SO2
how is this possible ?
and plz name the compounds and their valency

Answer 1

Hey...!! HERE IS YOUR ANSWER...!!

In the compound SO2, Oxygen can have -1 or -2 valence values, and S can have -1, -2, +2, +4 or +6 values but since there are two Oxygen molecules and one Sulfur molecule, each Oxygen molecule must have a value of -2 (total of -6) and each Sulfur molecule a value of +6 to balance to zero (-6 +6 = 0).

HOPE IT'S WILL HELP YOU A LOT...
