Answer 1

Answer:

it forms magnesium oxide

Answer 2

Magnesium burns easily in air when it is in its metal form. The magnesium metal, on the other hand, requires a source of energy to begin the reaction (burning).

Explanation:

• The flame supplies heat to the magnesium metal atoms, allowing them to overcome their activation energy.

• The lowest energy necessary for a chemical reaction to proceed is known as activation energy.

• To generate this powdery product, magnesium gives away two electrons to oxygen atoms.

• This is a reaction that produces heat. An exothermic reaction is one in which there is a net release of energy from a chemical reaction.
