(OPEC). There are various types of AFV designs in commercial use today‚ to include hybrid and flexible fuel designs. The most common are powered by compressed natural gas (CNG)‚ liquid petroleum gas (LPG)‚ propane‚ hydrogen‚ alcohol (in the form of methanol or denatured alcohol)‚ gasohol (blends of gasoline and up to 85% alcohol) and electric. These AFV types have been commercially available and in use by fleet applications in the U. S. since the 1960 ’s. Consumer availability of electric‚ propane and

Results and Discussion – Expt. 3 (Crystallization) Name: Parts A and B: 1. Please comment on the relative purity of your recrystallized salicylic acid (Hint: You should use your empirical data to support your claim). -The Salicylic acid that I obtained had a melting point range around 157-158 degrees Celsius for Part A. For Part B the melting point range was 156-157.5 degree Celsius. Part B‚ I would say the sample is less pure because of the notion that impurities lower the melting point

------------------------------------------------- ABSTRACT ------------------------------------------------- The copper reaction experiment was demonstrated by adding the reagents like 16M HNO3‚ Distilled water‚ 6M NaOH‚ 6M H2SO4‚ Acetone‚ Zinc metal and Methanol into the beaker with the copper wire. The experiment was also demonstrated to observe how copper reacts while different reagents were being added. It was also demonstrated to practice the common laboratory techniques such as methods of separation

Andrea Moreno 4 September 2015 Block B Calculations: There are no calculations. Analysis/ Critical Thinking Questions: Compare your data for the pure substances with the data for each of the two solid mixtures. Which of the pure substances shows behavior that is similar to what you saw with the the two-solid mixtures (Mixture 1 and Mixture 2)? If you cannot positively identify your mixture‚ discuss the possibilities for the mixture. The starch and mixture 2 are both similar because they both did
