Respuesta :
The equation which balances the given chemical reaction between magnesium and oxygen is 2Mg + O₂ → 2MgO.
What is balanced equation?
Balanced equations are those in which all of the entities on both the reactant and product sides are equal.
Given chemical reaction:
Mg + O₂ → MgO
Above reaction is not balanced as number of oxygens are not equal on both sides.
- Mg + 2O₂ → 4MgO
Because the amount of magnesium atoms is not equal, this is not a balanced equation.
- 2Mg + 2O₂ → 2MgO
Because the amount of oxygen atoms is not equal, this is not a balanced equation.
- 2Mg + O₂ → 2MgO
This is a balanced equation as number of each atoms are equal on both sides.
- 2Mg + 2O₂ → 4MgO
Because the amount of magnesium atoms is not equal, this is not a balanced equation.
Hence balanced equation is 2Mg + O₂ → 2MgO.
