A student performing this experiment followed all procedures carefully and correctly. The student observed a melting point of 128.5-131.0 °C for urea and melting point of 205.5-211.5 °C for anthracene. What should the student conclude? A. The thermometer is defective and should be replaced. B. That all future melting point data should be corrected by subtracting 6 °C from the observed melting point. OC. That the standards are impure and the experiment should be repeated with fresh standards. D. That all future melting point data should be corrected by adding 6 °C to the observed melting point.

(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. Insufficient dissolved oxygen is necessary for the life of fish and other aquatic organisms. As aquatic photosynthesis is light dependent, the dissolved oxygen produced will peak during daylight hours and decline at night. 2. The solubility of oxygen in water increases at colder temperatures, and decreases at higher temperatures. DO can be measured in milligrams of oxygen (O2) per liter of 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. When water is mixed with metals, a metal hydroxide is formed and oxygen gas is evolved. The evolution of the oxygen gas from the reaction of metals and water is indicated by the hastened…
