* Oxidation involves reacting with oxygen: When a metal is oxidized, it reacts with oxygen from the air.
* Different metals have different oxide ratios: The amount of oxygen that combines with a metal to form an oxide varies depending on the metal.
Example:
* Iron (Fe) + Oxygen (O2) → Iron Oxide (Fe2O3) (Rust)
* Sodium (Na) + Oxygen (O2) → Sodium Oxide (Na2O)
In the case of iron, the oxide (rust) is heavier than the original iron because a significant amount of oxygen has been added. In the case of sodium, the oxide is only slightly heavier than the original sodium.
To calculate the mass of the oxide, you would need:
1. The identity of the metal: Knowing the metal lets you determine the chemical formula of the oxide it forms.
2. The law of conservation of mass: The total mass of the reactants (metal + oxygen) must equal the total mass of the products (oxide).
Let me know the metal, and I can help you calculate the mass of the oxide!
