∙ 10y agoCHEMICAL energy converts to heat energy. The magnesium simply oxidizes very rapidly. The result can be either magnesium nitride or carbon dioxide, depending on whether it's burned in air or water.

The oxidation numbers of pure Mg and O2 are 0. During the reaction, the Mg is oxidized to a +2 oxidation number by the loss of 2 electrons, and O2 is reduced to a -2 oxidation number, as it gains the 2 electrons.

A reaction occurs when a substance reacts with oxygen to produce energy in the form of heat and light?
This is an oxidation reaction (combustion, burning).
What happens when you burn mg ribbon in air?
When Magnesium burns, it is actually combining with oxygen in the air to form a new compound, magnesium oxide. If we were to carefully weigh a piece of magnesium before and after burning it, you would see that its weight increased by about one third. For example, if you start with 100 grams of magnesium, after the burn you would end up with about 130 grams of magnesium oxide. The fact that the magnesium oxide you create by burning is powdery, means that it takes up more space (size or volume) than the solid magnesium did.

What energy given off by burning matchstick?
The energy given off by burning a matchstick is mainly in the form of heat and light. The heat is a result of the exothermic combustion reaction that occurs when the matchstick is ignited, and the light is emitted as a by-product of the combustion process.
What is the biological origin source of magnesium carbonate?
It occurs naturally in limestone. - Fiddy
Which of the following energy conversion occurs inside in a battery electrical to chemical thermal to electrical or thermal to chemical?
None of them Chemical energy stored in the battery is converted into Electrical (with some heat / thermal 'wasted'). However if you recharge a battery you would get electrical to Chemical.
Which energy conversion occurs in a battery-powered flashlight?
The conversion is from chemical energy to electricity to light energy.
Which energy conversion occurs in battery-powered flashlight?
