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. Since part A ‘s melting point was higher and closer to the melting point of the pure sample‚ it was more pure. The pure Salicylic acid that I got the melting point for had a range from 158-159 degrees Celsius. The impure

Optimal Growth Conditions and Generation Time for E. coli Introduction The goals of these exercises were to determine the optimal growing condition and the generation time of E. coli. Materials and Methods Please refer to the lab manual for a complete list of materials. To determine the optimal growth condition for E. coli‚ we had to test the environmental factors that could affect the growth. We tested the relative growth of E. coli in the presence and in the absence of oxygen. The results

Answer: To find out the slope‚ you must first take two separate points on the graph‚ such as (-5‚-1) and (0‚1). Then‚ it’s a simple matter to use the equation [pic] to find the slope: [pic]= [pic] 2. What is the slope of the line represented by the table of values below? How do you know? |x |y

Q-3. * Because the perfumed incense is in solid state and by lighting of it‚ it changes from solid state to gaseous state the moment it turns in to gaseous state and gases have a property to spread in all directions. After lightening the incense the molecules of perfume are in a gaseous state and mixing with the molecules of air in the room. All of them undergo random motion at all times as a result of the internal ("heat") energy that they have absorbed. The molecules often bump into each other
