Great job best explanation I’ve found

[@sophierobertson222]

You are great at explaining! I actually understand now!🎉

This is so great thanks so much!

TYY MAN UR SOO HELPFULL

[@abdulrahmanalmadani7168]

thank you it helped me a lot in my exam

[@jesssssssss7466]

Wouldn't the sodium oxide from the first example be aqueous according to solubility rules? I thought oxides were insoluble unless the compound contains a Group 1 metal or ammonium...

thank you!!

thank you! this was great

Thank You

thank you this helped a lot

Why did the i in the 2nd problem automatically become i2 is that just a rule ?

[@kelli5966]

i was just wondering the same thing. i guess iodine and hydrogen always get a 2? idk

[@yaboibablu]

ik this is very late, but its because they are diatomic elements. They are naturally always found in pairs, so we have to have H2 or I2

[@brianaalexandra]

hugh Jassole You probably forgot about this comment but all halogens and gases are diatomic when they are by themselves. Hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine are all diatomic so they always have the subscript of 2 when by themselves (:

[@theashologist]

​All Halogens in column VIIA are diatomic elements mostly in the form of gases (because they are gases. The other two elements that are diatomic but not considered halogens are Nitrogen and Oxygen

[@theashologist]

Be wary about Oxygen. Peroxide is O with a subscript of 2 and a superscript of -2 (O2^-2). But its oxidation state is of a -1 charge. This is the same with Mercury. Their is Mercury H2+ and Mercury (I) H2^+2 BUT its oxidation state has a +1 charge because its a variable metal.
