Question

1)Fe+ Cl2 → FeCl,
How to balance this
2)Fe+ O2 →Fe2O3
How to balance this

Answer 1

2Fe + Cl₂ -> 2FeCl
4Fe + 3O₂ -> 2Fe₂O₃

Answer 2

1. 2Fe + Cl2 ➡ 2FeCl

2. 4Fe + 3O2➡ 2Fe2O3

Step-by-step explanation:

1). )Fe + Cl2 → FeCl

Fe= 1 Cl=2 ➡ Fe= 1 Cl= 1

)Fe + Cl ➡ 2FeCl

Fe=1 Cl= 2 ➡ Fe=2 Cl=2

2Fe + Cl ➡ 2FeCl

Fe=2 Cl=2 ➡ Fe=2 Cl= 2

2). )Fe + O2 →Fe2O3

Fe=1 O= 2 ➡Fe= 2 O= 3

)Fe + O2 ➡2Fe2O3

Fe=1 O=2 ➡Fe=4 O=6

)4Fe + O2 ➡2Fe2O3

Fe= 4 O= 2 ➡Fe= 4 O= 6

)4Fe + 3O2 ➡2Fe2O3

Fe= 4 O= 6➡ Fe= 4 O= 6
