Okay I don't get this, if someone answers my questions I'll give them 10 points. I get everything except the sulphur oxide. I know they are covalent bonds, but why doesn't oxide have 'mono'? Would the sulphur oxide be S2O2, then reducing it be SO, or S2O, I'm confused. I don't get the covalent bonding, would the diatomic apply to covalent bonds? For example if both elements are negatives, such as sulphur and oxygen, when you combine them would oxygen have a 2 because its diatomic but then shouldn't it say dioxide why does it only say sulphur oxide? Okay so would the UNbalance equation be HS + O2 = H2O + SO?
