balancing equations?

Question

Mg^2+Cl2------> (Mg^2+) +Cl-
Magnesium + Chloride
balance--- 2Mg+Cl2-----> 3MgCl

Li+(OH-) +(K+2)+S^2- -------->(Li+2)(S^2-)+K+OH-
lithium hydroxide + potassium +silicon---->lithium sulfate + potassium hydroxide?
how do you balance?

Answer 1

I'm to lazy to do the math. Just count the number of atoms of each element on both sides, and multiply to balance the numbers.

BTW, this is a Chemistry question. Why is it in Physics?

Answer 2

2LiOH + K^2 + S^2 --> Li^2S^2 + 2 KOH
