Final answer:
Yes, there is more than one compound of magnesium and oxygen. One common compound is magnesium oxide (MgO), while another compound is magnesium peroxide (MgO2).
Step-by-step explanation:
Yes, there is more than one compound of magnesium and oxygen. One common compound is magnesium oxide (MgO), which is formed when two magnesium atoms combine with one oxygen molecule (O2) to produce two units of magnesium oxide. The balanced equation for this reaction is 2Mg + O2 → 2MgO. Another compound is magnesium peroxide (MgO2), which is formed when two magnesium atoms combine with two oxygen molecules to produce two units of magnesium peroxide.
