Question

This is the chemical equation for the production of ammonia (chemical formula: NH3) from Nitrogen and Hydrogen (N2 and H2):

Answer 1

Answer:

Honestly, I'm not even sure what the incorrect student was trying to do. The correct answer is:

( ) = the number of elements

(1)N2 and (3)H2

I think the student added the N2 and H2 to "balance" the chemical equation when instead they should have tried the balance the equation by making sure the atoms on the reactant side are equal to the atoms on the product side. You do this by multiplying the atoms on the reactant side until they equal the product side (not by adding them, as the student did).
