1)Fe+ Cl2 → FeCl,
How to balance this
2)Fe+ O2 →Fe2O3
How to balance this
2 answers:
2Fe + Cl₂ -> 2FeCl
4Fe + 3O₂ -> 2Fe₂O₃
Answer:
1. 2Fe + Cl2 ➡ 2FeCl
2. 4Fe + 3O2➡ 2Fe2O3
Explanation:
<u>1</u><u>)</u><u>.</u> )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
<u>2</u><u>)</u><u>.</u><u> </u>)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
