How would you balance: Mg3N2 + H2SO4 = MgSO4 + (NH4)2SO4?

Answer 1

You would balance it stoichiometrically. Garbage in must equal garbage out.

#Mg_3N_2 + 4H_2SO_4 rarr 3MgSO_4 + (NH_4)_2SO_4 #

Is the mass in the above equation balanced? My arithmetic is not very good!

LHS: #3xxMg, 2xxN, 8xxH, 4xxS, 16xxO.# RHS: #3xxMg, 2xxN, 8xxH, 4xxS, 16xxO.#

The equation is stoichiometrically balanced since the mass on the left side is exactly equal to the mass on the right side.

This treatment may appear a little awkward, but every chemist experiences this same process. This is something you go through every time you make a cash or electronic transaction; the credit to the merchant must match the debit to your account. If it doesn't, you will have to spend a lot of time on the phone with the merchant, complaining about the £99–99 debit that was made for your £9–99 purchase.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
