The balanced equations for the reaction of calcium (Ca) and magnesium (Mg) with oxygen (O2) can be written as follows:
- Balanced Equation for Calcium and Oxygen: 2Ca + O2 ⟶ 2CaO
In this reaction, two moles of calcium react with one mole of oxygen gas to form two moles of calcium oxide.
- Balanced Equation for Magnesium and Oxygen: 2Mg + O2 ⟶ 2MgO
Similarly, two moles of magnesium react with one mole of oxygen gas to produce two moles of magnesium oxide.
These balanced equations illustrate the combination of calcium and magnesium with oxygen to form their respective oxides.
