Balance this chemical formula
fe + cl2 = fecl3

First you find out how much each element has

Fe=1 * 2                    Fe=1
Cl=2  *3                   Cl=3 *2

now we multiply each so we can balance each side.

So now we get our balanced equation
2 Fe + 3 Cl2 = 2 FeCl3

Well to my expert knowledge and my exquisite calculations i think the the negative ion # 412 is the key to sucess

Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?
