Analysis of Oxygen bearing Organic compounds Abstract The Unknown sample in the experiment can be tested to yield results such as 1° (primary)‚ 2° (secondary)‚ 3° (tertiary) alcohols. Tests such as the dichromate test‚ Tollen’s test‚ Lucas test‚ DNPH test and iodoform test would be very useful in determining the type of alcohol that the unknown sample belongs to. In the experiment‚ the unknown sample underwent series of testing to identify what property of alcohol it belonged to and the result

The Modest Proposal In the modern China‚ the food that we are having is helping us to get closer to health. It gives us the chances to have a try to get many kinds of illnesses. The technology of production is developing sharply‚ there are a plenty of kinds of chemical way to make our food taste better and look more addicted. But not all of the addictive are OKAY for your bodies. For example‚ there was a piece of very famous news about milk powder. Sanlu milk powder was the hottest topic in 2008

notion include‚ that salmon are andromodus and inhabit the entire river ecosystem‚ from headwaters to the ocean. They are also extremely sensitive to changes in the ecosystem. Variables like water quality‚ trophic webs and upstream perturbations‚ turbidity and temperature all affect the salmon population. Usually‚ the more untouched and diverse their ecosystem is‚ the healthier the salmon population is. Thus‚ declines in the ability of salmon to reproduce and inhabit a watershed‚ indicate a decline

Experiment 1: Quantitative assessment of Some Cellular Constituents Summary: Euglena gracilis are unicellular organisms in the Protist Kingdom. They are known to have both plant and animal characteristics. Although‚ Euglena cells contain a variety of cellular constituents‚ their cellular constituents should be presented in equal ratio. The objective of this experiment is to determine Euglena’s cellular components in cells and then to establish their cellular constituents by comparing the experimental

EXPERIMENT 13： Extraction: Extraction with acid and alkali Objective 1. To recover the benzoic acid and p-dichlorobenzene from its mixture from its mixture by using acid-alkali extraction. 2. To determine the percentage recovery and melting point of the recovered benzoic acid and p-dichlorobenzene. Introduction Acid-base extraction is a process which purifying the acids and bases from mixtures based on their chemical properties. Acid-base extraction is performed to isolate the compounds and natural

Introduction The purpose of this project was to detect which organism we had in our unknown mixed culture tube by running a series of experiments to detect which specific Gram negative organism we had. To detect your gram positive from the mixed culture was given as extra credit points also. A Gram stain was performed and isolation streak plate in order to isolate and observe the unknown organism. Before the series of test‚ a dichotomous key had to be written up in order to know what steps

Imagine yourself observing one of the most diverse ecosystems on earth. Thousands of species of plants and animals provide a dizzying array of color and motion. Massive structures provide a canopy that shelters hundreds of exotic species in a myriad of microclimates. As land-based observers‚ we almost automatically assume that this is a description of the rich ecosystem of a tropical rainforest. However‚ if we take ourselves off the safety of dry land and immerse ourselves in the ocean‚ we
