Determine the concentrations of babr2, ba2 , and br– in a solution prepared by dissolving 1.18 × 10–4 g babr2 in 1.00 l of water. express all three concentrations in molarity. additionally, express the concentrations of the ionic species in parts per million (ppm).

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 .

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
