Question

If you balance the equation below, what should be the coefficient for lithium (Li)? Li + Cl2 LiClA.3B.1C.4D.2

Answer 1

xLi + Cl2 ---> xLiCl

You have 2 Cl, so at the end you need the same 2. If the resulting component is LiCl, you might have 2LiCl, so you spend the 2 initial Cl

Because of this, the result have 2 Li, so at the begining you have to have 2 Li.

D. 2
