Consider the balanced chemical equation, MgCl2(aq) + 2AgF(aq) → 2AgCl(s) + MgF2(aq) If both reactants are completely consumed and we produce 20 formula units of AgCl, how many ions of Mg and F did we start with? A) 10 ions of Mg and 20 ions of F B) 10 ions of Mg and 10 ions of F C) 20 ions of Mg and 10 ions of F D) 20 ions of Mg and 20 ions of F
