Magnesium continues to burn after oxygen is depleted. Thermodynamic properties of substances The solubility of the substances Periodic table of elements. Mg + H 2 SO 4 → MgSO 4 + H 2. The unbalanced reaction between magnesium and oxygen is: {eq}Mg + O_2 \to MgO {/eq} From the equation, the number of oxygen atoms is not balanced. The reaction of magnesium … So, you need to convert the 2.43 grams of Mg to moles. which of these elements is most likely to react with oxygen in a similar way? You may need to download version 2.0 now from the Chrome Web Store. Solution: Most of the metals react with oxygen to form metal oxides.
