1pt A sulfur atom contains 16 protons and 16 electrons. What must occur for this sulfur atom to become a sulfur ion with a charge of 2-? O A. It must lose two electrons.
OB. Nothing. It already has a charge of 2-
O C. It must gain two electrons.
OD. It must lose two protons.

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .
