9:37 ® d y LABORATORY-ACTIVITY-4 - Saved 目 LABORATORY ACTIVITY 4 PHYSICAL PROPERTIES OF MATTER I. OVERVIEW A physical property is a characteristic that can be observed and measured without changing the identity and composition of the substance. Examples of physical properties are color, melting point, and boiling point. Physical properties are very important because these help chemists in identifying substances. For example, a clear, colorless liquid observed to boil at 100 and freeze at OE would definitely be water. Water undergoes physical change wherein its physical appearance changes but its composition remains unchanged. I. ОВIЕСTIVES 1. To be able to determine the physical properties of matter. III. MATERIALS 1 long liwanag candle (remove the tip and cut into 2-inch, 3-inch, and 4-inch long) 3 iron nails (1-inch, 2-inch, and 4-inch long) Water Clear straight glass (calibrate: 1mm = 1 mL) Weighing scale IV. PROCEDURE 1. Describe the hardness and color of the candle and iron nails.…

(A) if both sentences are true, (B) if both sentences are false, (C) if the first sentence is true but the second is false, and (D) if the first sentence is false but the second is true. 1. Water appears in nature in all three common states of matter. Water is a tasteless, odorless liquid at standard temperature and pressure. 2.  The addition of salt in the distilling mixture made the water impure and saline. The addition of 5 drops of the silver nitrate solution into the distillate determines whether the distillate is impure or pure water. 3. The ideal electrical conductivity of totally pure water is 0.055 microSiemens, whereas typical deionized water has an electrical conductivity of 0.1 microSiemens. The freezing point of water at 1 atm is 100degC.  4.  From the air, oxygen can slowly diffuse across the water’s surface from the surrounding atmosphere, or be mixed in quickly through aeration, whether natural or man-made. The aeration of water can be caused by wind (creating waves),…

Assume that you have isolated 1.500 grams of benzoin from Step 1 of the Dilantin experiment. The laboratory manual states that you need to add 1.25 equivalents of pulverized ammonium nitrate (as compared to benzoin) to your reaction flask. How many grams of ammonium nitrate would you add? Use the Physical Data below. Physical Data Benzoin | MW = 212.25 g/mol Ammonium Nitrate MW = 80.04 g/mol grams (just place a number in the blank, no labels).

Q2. Two widely used pain relievers are aspirin and acetaminophen (Tylenol). “Liquid” Children's Tylenol® is simply acetaminophen suspended in fruit-flavored sugar water with food coloring and an acid buffer. As you may know, "children's medications" are big money makers for pharmaceutical companies. Despite this fact, the liquid form of Children's Aspirin is NOT commercially available.
