A good reaction that gives off a bright light occurs when magnesium is burned in a bunsen burner. As a result, it binds with oxygen in the air. What is the balanced chemical equation for this reaction?

Magnesium when reacts with air produces magnesium oxide or MgO. In balancing reactions, it is important to know that the number of atoms at each side should be equal.

2Mg + O2 = 2MgO

Hope this answers the question. Have a nice day.
