Fe +
Cl2 = FeCl3
(1 point)
DA. 2, 3,2
1
C. 1, 1, 1, (already balanced)
D. 4,6,4
E. 2, 1, 2
tea
B. 1, 2,​

Answer 1

Option A. 2, 3, 2

Step-by-step explanation:

We'll begin by balancing the equation. This can be achieved by doing the following:

Fe + Cl2 —> FeCl3

There are 2 atoms of Cl on the left side and 3 atoms on the right side. It can be balance by putting 3 in front of Cl2 and 2 in front of FeCl3 as shown below:

Fe + 3Cl2 —> 2FeCl3

There are 2 atoms of Fe on the right side and 1 atom on the left side. It can be balance by putting 2 in front of Fe as shown below:

2Fe + 3Cl2 —> 2FeCl3

Now the equation is balanced.

The coefficients are : 2, 3, 2
