N₂ + H₂ → NH₃

is actually not balanced. The correct balanced equation for the formation of ammonia (NH₃) from nitrogen (N₂) and hydrogen (H₂) is:

N₂ + 3H₂ → 2NH₃

Now, let's determine the type of chemical reaction:

This reaction is a combination reaction (also known as a synthesis reaction). Here's why:

* Two or more reactants combine to form a single product. In this case, nitrogen gas (N₂) and hydrogen gas (H₂) combine to form ammonia (NH₃).
