hi

Im just wondering... When you write half equation, net and complete ionic equations, do you have to take into consideration the diatomic molecules ie- oxygen, nitrogen, chlorine etc.? Or do you treat them as a single atom?

Thanks ​

You have to consider them.

So when writing a half equation for oxygen it has to be O2 + 4e---> 2O2- ? I'm not sure if it's correct but hopefully it makes sense

Yep.

Yes. At the end of the day, all equations must be balanced, both by stoichiometrics and by charge.

What does "stoichiometrics" mean?

Im pretty sure u count them regardless of the matter.
All halogens.

Measurements and calculations of quanitity, I think.

a "stoichiometric" reaction is where all of the products are used up e.g 2 mol Hydrogen gas reacts with 1 mol of oxygen gas to form 1 mole of water. In a stochiometric reaction there is no limiting reagent.

Or alternatively you can write:
O + 2e ---> .502

OR u could just say stoichiometrics is simply what u do with moles and calculation of quantities lol
