1. Calculate the hydronium-ion concentration: (9 points) а. b. apple juice, pOH = 10.24 pH [OH] saliva, antacid, = 7.45 1.51 x 10 с. 2. A lamp draws a current of 2.0 A.Find the charge in coulombs used by the lamp in 30 s. (3 points) How much heat is required to raise the temperature of 10.0 g of H,O(s) from -10°C to H,O(1) at 10°C? (3points) 3. 4 What are the boiling point and freezing point of a solution prepared by dissolving 2.40g of biphenyl, (C12H10) in 75.0g of benzene, (CoHo)? The molal weight of biphenyl is 154g/mol. (5 points) Kb for benzene = 2.53 °C/m BPbenzene = 80.1°C Kf for benzene = 5.12 °C/m FPbenzene = 5.5°C

. In performing the lab reaction, the student made a mixture of 3 reaction components in a beaker. This was done by mixing 13.00 mL of 0.00250 M Fe³(aq) with 11.00 mL of 0.00250 M SCN (aq) and 6.00 ml. of deionized H₂O. Upon mixing these solutions (total volume of 30.00 mL), the final solution turned a deep. red color. The absorbance of this equilibrium mixture was measured and the concentration of Fe(SCN)2 was determined to be 3.00 x 10 M with the use of the Beer's Law constant (k). Determine the equilibrium constant (K) for the reaction from these values by completing the ICE table below. Be sure to report your final value of K at the bottom.
