Question

Balance the following chemical equation

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

Answer 1

Step-by-step 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
