Answer:
3Mg + Fe₂O₃ → 2 Fe + 3MgO
Explanation:
Chemical equation;
Mg + Fe₂O₃ → Fe + MgO
Balanced Chemical equation;
3Mg + Fe₂O₃ → 2Fe + 3MgO
This is the balanced equation. There are three magnesium, two iron and three oxygen atoms are on both side of equation thus it follow the law of conservation of mass.
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
The scratched tin can with the iron will more rapidly corrode the iron than the tin.
<h3>What is corrosion?</h3>
The corrosion can be given as the process of the oxidation of the metal into the more stable metal oxide. The chemical oxidation of the metal is attained with the surrounding available oxygen or the water vapors.
The reactivity of the Iron for the oxidation is more as compared to the tin from the reactivity series. Therefore if both tin and iron are exposed to corrosion, iron will be more rapidly corroded.
