Mg²+ 2OH 16. In a saturated solution of Mg(OH), at 21°C, the concentration of OH is 2.50 X 10° M. The equilibrium is represented by the following equation: Mg(OH)2 Write the expression for the solubility-product constant, K. and calculate its value under these conditions. Note: Show all calculations, follow the rules of significant figures, and box your final answer. (3 marks) 17. A chemical reaction involves the combination of 0.200 mol of hydrogen and 0.200 mol of nitrogen in a rigid 2.00 L container at 773 K, represented by the following equation: 3H₂(g) + N₂(g) + 2NH₂(g). At equilibrium the system contains 0.050 mol of ammonia. Use an ICE table to determine the equilibrium concentrations of hydrogen and nitrogen. Note: Show all calculations, follow the rules of significant figures, and box your final answer. (3 marks)
