Why does magnesium burn with a white flame? What does it say about the electron transitions that take place?
Answered by DrBob222
The reaction of Mg with oxygen of the air produces heat. It takes more energy to produce white light than red light.

Answered by DrBob222
Yes. When a reaction gives off heat it is said to be exothermic and the enthalpy of the reaction is negative.
