Why does a magnesium ribbon burn with a dazzling white flame?

Answer 1

When burned in air with a Bunsen burner it produces a bright white flame/light. Never look directly at it as it will hurt your eyes. After burning they produce magnesium oxide. here's an equation for it :

2Mg + O2 -----> 2MgO

Answer 2

Magnesium ribbon burns with a dazzling white flame because of the high temperature of the combustion reaction, which produces a large amount of energy in the form of heat and light. The intense white light is a result of the high energy emission from magnesium atoms as they undergo combustion and form magnesium oxide.

Answer 3

Magnesium undergoes a chemical reaction when it burns: It combines with oxygen out of the atmosphere to form magnesium oxide (MgO), which has more mass than the Mg alone. The Atomic Mass of magnesium is 24.3, but the molecular mass of MgO is 40.3 (24.3 + 16.0).

Answer 4

It reacts with the oxygen and nitrogen in the air, when it reaches a certain temperature. This makes a compound changing its physical characteristics.

Answer 5

Because after burning magnesium is transformed in magnesium oxide (MgO) with a higher molar mass.

Answer 6

Because it burns very hot.
