Magnesium (Mg) and oxygen (O2) react to form magnesium oxide (MgO). Which type of chemical reaction does the equation represent?

Synthesis

Explanation:

A synthesis chemical reaction is where two simpler substances form together to create a more complex product.

The reactants can be either a single element or a compound, but the product is always a compound.

Since Mg and O2 reacted to create MgO, a compound, this represents a synthesis reaction.
