Question

Balance the following chemical equation
1. Fe + Cl2 → FeCl3
2. H2O2 -> H2O + O2
3. Ca + O Cao
4. Al + 02 - Al2O3

Answer 1

Answer:

Explanation:

Chemical equation:

Fe + Cl₂ →  FeCl₃

Balanced chemical equation:

2Fe + 3Cl₂ →  2FeCl₃

Chemical equation:

H₂O₂   →   H₂O + O₂

Balanced chemical equation:

2H₂O₂   →   2H₂O + O₂

Chemical equation:

Ca + O →  CaO

Balanced chemical equation:

Ca + O →  CaO

Chemical equation:

Al + O₂ →   Al₂O₃

Balanced chemical equation:

4Al + 3O₂ →   2Al₂O₃
