The purpose of our experiment was to synthesize aspirin from acetyl anhydride‚ salicylic acid‚ and sulfuric acid. And then determine the relative purity of the synthesized sample. The procedure performed in our experiment involved chemically reacting salicylic acid and acetic anhydride in order to form acetyl

Nissan Leaf Every time you coast or apply the brakes in the Nissan LEAF® the electric motor acts as an electric generator‚ converting energy that would otherwise be wasted into battery energy. So even when you’re slowing down‚ you’re charging up. The Nissan LEAF® gets the equivalent of 130 miles per gallon. That’s right‚ 130 miles per gallon. [*] How does it achieve these remarkable numbers? With a 100% electric drive system powered by an advanced rechargeable lithium-ion battery‚ and nine range-maximizing

Lab 1‚ Exercise 1 • Based on the information in Table 2‚ what patterns do you observe? The number of fish that I observed in a body of water increases until the dissolved oxygen was at 12 ppm. After that point‚ the number of fish declines slightly. • Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. When the dissolved oxygen levels increase‚ the number of fish that

Lab 5 DECOMPOSITION (Nov 2‚ 2011) Introduction: Decomposition is the breakdown of organic material into its smaller molecules and elements. (This term is generally considered as a biotic process but one may find it also used to describe an abiotic process‚ e.g.‚ due to weathering.) The decomposing organisms may use the release of elements for nutrients and by breaking apart the carbon-carbon bonds in organic matter this can release energy for them. These smaller molecules and nutrient elements

Stem and Leaf Plots Examples 1. A stem and leaf plot is a method used to organize statistical data. The greatest common place value of the data is used to form the stem. The next greatest common place value is used to form the leaves. 17 stem leaf 2. EXAMPLE: Make a stem and leaf plot of the algebra test scores given below.

Plants were cut at the soil surface‚ leaves were separated from the plants‚ covered with blotting paper to keep the leaf intact and retain its original shape and were brought to the laboratory.
