Question

The burning of magnesium involves a conversion of

Answer 1

chemical energy to heat energy
because magnesium harbours potential energy, which in this case is chemical energy, and when it is burned it produces energy as heat.

Answer 2

Chemical energy to heat energy

Step-by-step explanation:

Magnesium metal when exposed to flame, it react with the oxygen in air to form white colored powered, known as magnesium oxide with the evolve of heat.

The balanced chemical reaction is shown below as:-

`2Mg+O_2\rightarrow 2MgO`

In the reaction the chemical energy which is stored in the chemical bonds of the magnesium and oxygen gas releases which makes the molecules surrounding the system gets heat up and thus, changes to thermal or heat energy.

Thus, The burning of magnesium involves a conversion of chemical energy to heat energy.
