Chemotherapeutic Agents of Control: Introduction: Chemotherapeutic agents are chemical substances used to treat various forms of infectious diseases. The chemotherapeutic agent works by stopping the bacteria from reproducing. There are two different kinds of chemotherapeutic agents. The first kind is an antibiotic‚ which slow down the growth of microorganisms. The second kind of chemotherapeutic agent is synthetic drugs. Synthetic drugs are artificially made in a laboratory.

ethylenediamine is added into the flask. 3. A vigorous stream of air is being drawn through the solution for about 1-2 hours 4. 35ml of concentrated hydrochloric acid is added 5. The solution is then being evaporated on a steam bath until a crust forms over the surface. 6. The solution is cooled and stand overnight before the bright green plates of the hydrochloride‚ trans-[Coen2Cl2]Cl.HCl is filtered 7. During filtered process‚ the product is washed with ethanol and ether before dried at 110 °C

Abstract: This report presents the reason why the ocean does not freeze in the winter. Since the ocean consists of salt water‚ an experiment was done to test the effect of freezing on salt water compared to pure water. The experiment was conducted three times in order to obtain accurate results and eliminate errors. In addition to the salt and pure water experiment‚ a variation of this experiment was created to test other options. In the variation experiment the effect of freezing on sugar water

Questions and Hypothesis: Seed germination‚ plant growth‚ and sprouting of leaves are affected by several factors: supply of nutrients‚ water‚ exposure to sunlight‚ and conditions of surroundings. Due to certain stimuli in the surroundings plant “hormones” cause plants to behave in ways that ensure the most efficient use of resources while preserving the most energy. One stimulus to consider‚ is the exposure of plants to sunlight; when plants are just sprouting and are underground‚ the sti

Ions are atoms that have (pick one): gained or lost; shared one or more electrons into or form their valence shells. 16. A cation is an atom that has (gained or lost) an electron. (Pick one) 17. An anion is an atom that has (gained or lost) an electron (Pick one) 18. When a cation bonds with an anion‚ that bond is referred to as a/an _ionic_

Investigate the effect of temperature on the rate of respiration of various parts of plants (germinating seeds and dormant (non-germinating) seeds)‚ by measuring the oxygen consumption and change in gas volume of respirometers containing either germinating or non-germinating seeds at different temperatures to measure the rate of respiration of these beans at different temperatures. Hypothesis 1.Germinating seeds have a higher rate of respiration as compared to non-germinating seeds and the glass

precipitate. Starting out the experiment‚ HCl was added to the solution in the test-tube in order to form a reaction between the HCl‚ Ag‚ Pb‚ and Hg cations. The products of this addition of HCl were PbCl2‚ AgCl‚ and Hg2Cl2. After the HCl was added‚ the solution turned a milky white color. It was important to not add too much HCl because excess HCl would have caused an aqueous complex of PbCl2 and AgCl to form instead of the desired solid PbCl2. The mixture was then centrifuged in order to let the solid

carried out by adding benzaldehyde and acetone into a flask. The product created is a 1‚5-diphenyl-1‚4-pentdiene-3-one‚ which includes two double bonds‚ and two benzyl ring functional groups. This is a dehydration reaction that occurs twice in order to form the diene. After obtaining the product‚ via vacuum filtration‚ it will be recrystallized and then analyzed for purity by determining both products’ melting point. The two products will be compared.
