Answer:

#"N"_2(g) + 3"H"_2(g) rightleftharpoons 2"NH"_3(g)#

Explanation:

The Haber process is arguably one of the most important chemical processes in the industrial world. In the process, nitrogen gas and hydrogen gas combine to form ammonia:

#"N"_2(g) + "H"_2(g) rightleftharpoons "NH"_3(g)# (unbalanced)

To balance this equation, let's start by placing a coefficient of #color(red)(2# in front of #"NH"_3# to balance the nitrogen:

#"N"_2(g) + "H"_2(g) rightleftharpoons color(red)(2)"NH"_3(g)# (unbalanced)

Now we notice there are #6# hydrogens on the right and #2# on the left. To fix this, we simply place a #color(blue)(3# in front of the #"H"_2#:

#"N"_2(g) + color(blue)(3)"H"_2(g) rightleftharpoons color(red)(2)"NH"_3(g)# (balanced)

And our equation is balanced:)
