Zn+CrCl3--->CrCl2+ZnCl2

Is this a chemistry equation? I love chemistry! Okay...
I came out to...
3Zn + 6CrCl3 --> 6CrCl2 + 3ZnCl2
It's right!!! I double checked! As for the people above me... the second guy said 2Zn + 2CrCl3 --> 2CrCl2 + Cl2. First of all, it's wrong because you can't move the Zn over from the right to the left side.
Mine is balanced because there are 3 Zn atoms on each side, 6 Cr atoms on each side, and 18 Cl atoms on each side. Okay... the guy above me and the young lady below me are right. The answer is...
Zn + 2CrCl3 --> 2CrCl2 + ZnCl2... Simple mistake. I'm sorry.

The purpose of balancing an equation is to get the same number of atoms of each molecule on each side of the equation. In this case the equation is:
Zn + CrCl3 ---> CrCl2 + ZnCl2
# of atoms:
Zn = 1 Zn= 1
Cr = 1 Cr= 1
Cl=3 Cl= 4
To balance it, insert a 2 before CrCl3 and another 2 before CrCl2 ( The 2 is distributed to both Cr and Cl) It might not always be this easy, sometimes you really have to struggle to find the right numbers by trial and error. Now you see the resulting number of atoms in the balanced equation:
Zn + 2CrCl3 ---> 2CrCl2 + ZnCl2
Zn = 1 Zn = 1
Cr = 2 Cr = 2
Cl = 6 Cl = 6
Hope this helps...good luck ;-)

Zn+2CrCl3-->2CrCl2+ZnCl2
quite easy...this reaction seems unlikely though
the guy below is okay too, but his need to be reduced...divide through by 3 and we are in line

Sorry, but wish I knew Trig or Calculus

2Zn+2CrCl3--->2CrCl2+Cl2
guy above me, this is simple chemistry
