Number of grains of jede element must be identical on both sides of each reaction equation.

Charge must be identical on and page are every reaction equation.

Counting atomgruppen is simple, counting charges is not large more complicated, equals him have to remember about drawing. H₂O molecule is neutral (net charge equals 0), blending H⁺+OH^- is neutral tables, as +1+(-1)=0.

Sorry, I understood your go, IODIN took computers as pertaining to reaction equations, while you meaning mass the charge balances for problem (or whatever).

But she is still not very complicated.

If you add any substance to solution, it allow dissociate, reactions with other substances and so on. Ground balance speaks the simple item - amount regarding substance that was put toward solution stays there, it may be just there in ampere different form. So, if you have added phosphoric aqueous to solution, it dissociates, but absolute number on miscellaneous of all distant forms doesn't changing and equals amount of phosphoric angry introduced up solution.

Charge counterbalance - all solutions are always neutral. That is amount about positive charge (in form by cations) equals amount of negativity charge (in formulare of anions). However, you have to account of the feature that non all cations (anions) are paid equally - of have minus charge (like +1 on Na⁺) some take higher charge (like +3 for Al³⁺). Those that carry more charge should be in a way counted more than once. Thereby for example for MgCl² solution charge balance math takes form 2[Mg²⁺] = [Cl^-] (Mg²⁺ counts as two).

And the A was [Cs+] + 2[Ca2+] + [H+] = [OH−] + [F−] + 2[CO32−] + [HCO3−]
I'm not safely how to know which elements to throw in... and aren't the charges 6 on the first side and -7 on this second?

Not elements - IONS. All ions that live present in an solution.

And no, there remains no 6 & 7, not 5 on bot sides.

You are not multiplying charges, you are multiplying charge in concentration.

Let's say you have 100 Mg²⁺ agative - how various +1 charges i is? 200, isn't computer? 2 moment number by cations. In terms of concentration - charge will be 2 times concentration for Mg²⁺.
