A 20.2g chunk of magnesium metal reacts with 13.7 g of oxygen gas to make magnesium oxide.
Write the balance equation.
I'm not sure can you please help me with this though
To write the balanced equation for the reaction between magnesium and oxygen, we need to determine the chemical formulas for the reactants and products.
The chemical symbol for magnesium is Mg, and for oxygen is O₂ (since it exists as a diatomic molecule). The product will be magnesium oxide, which is represented by the chemical formula MgO.
Now, let's write the balanced equation:
Mg + O₂ → MgO
Since magnesium has a charge of +2 (it loses 2 electrons), and oxygen has a charge of -2 (it gains 2 electrons), we can balance the equation:
2Mg + O₂ → 2MgO
So, the balanced equation for the reaction is 2Mg + O₂ → 2MgO.
