No, it's a cation.
Cat(ion)s have Paws(itive charges)

The compound FeF3 is a salt, meaning that it has a covalent bond. Split the anion and the cation apart to determine the charge. Since iron can be either +2 or +3, you have to look at the anion (F- in this case) and look at how many negative charges are there. If there are three F-, that means there are three negative charges. That should tell you which iron is involved in the bond.
MgCl2 aq plus Zn s is the oxidation half-reaction for Mg s plus ZnCl2 aq.
12.5 mg * 2 = 25.0 mg.
Absallutly!
Neither, heluim is inert, one of the noble gases.
mg + CuCl2 + MgCl2 + Cu Mg + Cu^+2 = Mg^+2 + Cu

The chemical equation is:Mg(NO3)2 + 2 NaOH = Mg(OH)2(s)+ 2 NaNO3
The chemical formula of carbonate anion is (CO3)2-.The chemical formula of magnesium cation is Mg2+.
The oxidation state of magnesium in magnesium hydroxide is +2 no matter what reaction you are looking at.
The oxidation state of magnesium in magnesium hydroxide is +2 no matter what reaction you are looking at.
The oxidation state of magnesium in magnesium hydroxide is +2 no matter what reaction you are looking at.
They simply form Mg(OH)2

The cation,Mg 2+andthe anion,O 2-combine to form,MgO------------------magnesium oxide
A negative charge. Cl^- , O^2- , N^3- etc., are anions. By comparison, Na^+ ., Mg^2+ . Al^3+ etc., are cations. Collectively , anions, and cations are named as 'ions'.
