3) Show work. Ammonium sulfate is used in soil fertilizers. a) Write a balanced equation for the dissolution of solid ammonium sulfate in water. b) Does this solution conduct an electric current? Explain your answer. c) A solution is prepared by dissolving 12.4g ammonium sulfate in enough water to make 100.0mL of stock solution. A 10.00mL sample of this stock solution is added to 75.00mL of water. Calculate the concentration of ammonium ions in the final solution. [0.221M] d) Urea, CO(NH2)2, is also used in soil fertilizers. If urea was dissolved in water, would this solution conduct an electrical current? Explain your
