Record what you observed when silver nitrate was added to the following: (a) Potassium chloride solution (b) Potassium chlorate solution (c) Residue solution 2. (a) What evidence did you observe that would lead you to believe that the residue was potassium chloride? (b) What would happen if you added silver nitrate to a solution of sodium chloride? Explain your answer. e) Did...
Consider the combination reaction between aluminum metal and liquid bromine (d = 3.1028 g/mL). Also consider that you have 38.4 g of aluminum metal and 40.6 g of bromine liquid. For this reaction AHrxn = -526 kJ/mol. If you were able to measure 15.5 kJ of heat being dissipated from this reaction, what would you expect to be the percent yield based on the heat generated? Hint: Find the limiting reagent before calculating the theoretical yield of the reaction.
17. (10 pts) Solid potassium metal reacts with liquid water to produce aqueous potassium hydroxide and hydrogen gas as shown by the BALANCED chemical equation below. When a 3.50 g piece of K(s) is added to 150. g of water in an insulated container, the temperature of the liquid INCREASES from 25.0 °C to 65.8 °C. Calculate the enthalpy of reaction (4FH) for the reaction in the forward direction. Water has a heat capacity (Cp) of 4.18 J/(8 °C). Assume...
