The 2 equals the different charge of the ions; the connection itself is uncharged.

Yes, except you write a loaded complex ion yourself, then the load of the ion must come out.

Depends on the charge of the iron ion and the sulfation is explained by the valency of the sulfur (sulphide, sulfur, sulfite, sulfate) and oxygen.

In the case of salts, it doesn’t matter whether an ion consists only of one atom or of several atoms. It is only important that it is a stable ion.

And the OH anion has the charge -1. You need two of them to balance the +2 charge of a Ca cation. A “substance” you can touch is always charge-neutral!

The clamp works exactly as in math. What is in the clamp is multiplied in one piece.

Because it is from a Ca and 2 OH is formed

Ca

OH

Because it’s CaO + H2O → Ca(OH)2 you need the 2 because otherwise it doesn’t work
