Answer 2

Answer:

2FeCl2 + Cl2 ----->  2FeCl3

Explanation:

FeCl2 + Cl2 ----->  FeCl3

first see iron is balanced

so proceed to balance Cl

on LHS we have 4 Cl atoms

on RHS we have 3 Cl atoms

multiply FeCl3 in RHS with 4/3

FeCl2 + Cl2 -----> 4/3FeCl3

to get integral stoichiometric coefficient multiply whole equation with 3

3FeCl2  +  3Cl2 ----->  4FeCl3

NOW again balance Fe by multiplying FeCl2 in LHS with 4 and FeCl3 in RHS with 3

(4) x 3FeCl2  +  3Cl2 ----->  (3) x 4FeCl3

12FeCl2  +  3Cl2 ----->  12FeCl3

as you can see above we have balanced Fe

count no. of Cl atoms on both sides

On LHS we have 24+6=30

On RHS we have 12*3=36

To balance Cl atoms multiply Cl2 in LHS with 2

12FeCl2  + (2) x 3Cl2 ----->  12FeCl3

12FeCl2  +  6Cl2 ----->  12FeCl3

we have a balanced equation

now you can simplify the stoichiometric coefficient and reduce it down by dividing the whole equation by 6

2FeCl2  +  Cl2 ----->  2FeCl3 {balanced equation}

Hope it helps ;)
