when we charge the mobile battery, then electical energy get convertad to chemical energy.
Yes. It is possible when the charge on the ions are different. For example the reactions will be different for Fe2+ and Fe3+
it is written as the chemical initial with a + next to it for example, hydrogen would be H+ ion.
A battery making or giving something a charge to make it move
-1 charge
it has it's symbol and valency as IO and -2 respectively. for example the formula of calcium iodate is CaIO.
The chemical symbol for calcium is Ca. The charge however, is neutral.
The chemical name for C2O4 with a charge of -2 is Oxalate.
The chemical symbol for oxygen is "O" and it typically has a charge of -2.
Your telling me!
i believe it represents the overall charge after the atom becomes an ion
which is an example pf chemical large
