A pure sample of (R)-limonene has a specific rotation of +125.6\deg . If a sample had a specific rotation of +80.4\deg , how much of each enantiomer is present in the sample? Show your work. Why is a large excess of water used in the distilling flask in the steam distillation of limonene? After your chemical tests how would you expect the IR to change? What would be the molecular formula of the product when excess Br2 reacts with limonene? Explain.

Part A) For procedure five, write the reaction that occurred when you brought the glowing splint/match to the mouth of the test-tube. (Hint: Consider which product from the reaction of HCl and Zinc is present at the mouth of the test-tube.)Procedure 5: Add 2 mL (40 drops) of 6 M hydrochloric acid (HCl) to the test tube. CAUTION: HCl is corrosive. Keep it off your skin. If you spill acid on yourself immediately flush the affected area with water for 2-3 minutes and notify your instructor. Drop one small piece of zinc into the test tube. When the bubbling begins hold an empty test tube over the mouth of the reaction tube. After a minute, insert a glowing splint to the mouth of the empty test tube. Record your observations. Discard the used zinc in the waste container.Part B) please write the complete reaction for the second procedure: AND the net ionic reaction as well.Procedure 2: Add 1-2 mL (20-40 drops) of silver nitrate (AgNO3) solution to a test tube. CAUTION: Silver nitrate is a skin irritant. Keep it off your skin. Place a small piece of copper wire into the silver nitrate solution. Note any changes to the copper wire and the solution over 10-15 minutes.Part C) please write the complete reaction for the forth procedureProcedure 4: Heat a small sample of solid copper (II) sulfate pentahydrate (CuSO4•5H2O) in a test tube. Remember not to point the mouth of the test tube at yourself or anyone else. Copper (II) sulfate is a skin irritant. Avoid contact with this chemical. Heat only the bottom of the tube where the crystals are located. Tilt the test tube at an angle while heating. Describe any change in the solid left in the test tube after heating. Add 5 drops of distilled water to the solid left in the test tube. Record your observations.
