    "Identify the number and types of atoms in balanced chemical equations."

    I don't understand, I know what balanced chemical equations are but how do I answer this question?

    Thank you

    Consider this equation for the Haber process:
    N2 + 3H2 → 2NH3

    Look at the reactants. What atoms are involved?
    • 2 nitrogen atoms (which are bound together in a nitrogen molecule)
    • 6 hydrogen atoms (which are bound two by two in three hydrogen molecules)

    That's 8 atoms! You get the same if you count the atoms in the products (conservation of mass).
    Of course, this is correct at a molecular level only. If you have specified amounts of substance, you can use Avogadro's constant in a similar way.

    Thank you so much, you are a life saver!! I understand now.
