Question

Write a word equation for the reaction of magnesium with oxygen.

Answer 1

$2Mg\left(s\right)+O_2\left(g\right)\to 2MgO$

Explanation:

First, we need to identify the type of bond and reaction. This is an ionic bond so atoms are giving and accepting electrons. This is a synthesis reaction.

Magnesium has a charge of 2+, while oxygen has a charge of 2−. The burning of magnesium metal reacts with oxygen found in the air (oxygen gas) to form magnesium oxide.

$2Mg\left(s\right)+O_2\left(g\right)\to 2MgO$

Oxygen is a diatomic molecule and is almost always reacting with elements as a gas, $O_2$ .

Here is a short video showing the reaction of magnesium and oxygen. The white ash and smoke formed in the reaction is the magnesium oxide.
