Balance the following equation? Al + O2 - - - - - -) Al2O3

4Al (s) + 3O₂ (g) → 2Al₂O₃

General Formulas and Concepts:

Chemistry - Reactions

Explanation:

Step 1: Define RxN

Al (s) + O₂ (g) → Al₂O₃

Step 2: Balance RxN

4Al (s) + 3O₂ (g) → 2Al₂O₃

chemists can use the electron cloud model to assign electrons to different atomic orbitals. atomic orbitals also explain the patterns in the periodic table

explanation:

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
