Organic Chemistry II Laboratory (ABCT357) Although studying fundamental theories of chemistry in the class is important to understand the concept of chemistry‚ carrying out experiments to corroborate the theories is also important. It is very important for students to get used to experiments in order to speed up their experiments. Expt.1. Acetylation of α-D-glucopyranose Add slowly 2.5 g (0.014 mol) of powdered D-glucose in small portions (roughly in 7-10 portions and 5 min for each addition)

ABSTRACT OBJECTIVE To learn the concept of separating organic compounds by utilizing the concept of acid/base chemistry in so that separation can be done. INTRODUCTION Using acid base chemistry in the separation of substances can be a quite useful technique in organic chemistry. A basic extraction can be carried out by applying a hot solvent such as water to a dry substance like coffee. This will allow for the extraction of caffeine and flavor from the coffee beans. Acid base chemistry can be

Proteins and enzymes are also affected by temperature changes. Oxygen is essential for the production of ATP from nutrients in cells; consequently oxygen must be delivered to a cell in sufficient amounts. Within fish‚ the counter-current exchange system allows for the efficient extraction of oxygen from the water by the gills. Basically when a fish takes in water‚ the flow of it is opposite to the flow of blood. As they rush by each other oxygen from the water is given to the blood (metabolic rate is also

Study of Oxygen Consumption to Measure Energy Metabolism in Mammals Brianne Simonsen Lab Section 8 4 Oct. 2005 Abstract In this experiment the oxygen consumption of a mouse in environments of varying temperatures was studied. The hypothesis behind this experiment was that more oxygen would be consumed at a lower temperature to maintain body heat. To measure the rate of oxygen consumption a mouse was given a specific amount of oxygen. The amount consumed in a specific time was measured and

KINESTHETIC‚ (STATIC) EQUILIBRIUM AND ORGANIC SENSES * STATIC EQUILIBRIUM Equilibrium or balance monitors the position and movement of the whole body. In a strict sense‚ inner ear is the biological gyroscopes for sense of balance. EQUILIBRIUM * Hair cells in the vestibular membrane or semicircular canals of the inner ear are receptors for balancing. Vestibular sacs which connect the canals with the cochlea are substances that move when the head rotates or tilts. * Head movements

Experiment 6 titled “Organic Chemistry” and the purpose of this lab is to get familiar with some organic functional group and test certain reactions of selected functional groups. To do the first part of the experiment (combustion test)‚ instructor demonstration in hood‚ and record the observation. Part A (combustion of toluene) pour 1 milliliter of toluene into a evaporating dish and ignite it with a flaming wood splint. Most importantly put the flame with a watchglass. Part B (combustion of ethyl

price of organic food is involved as a factor for consideration to purchase organic food. Many consumers consider the price of organic food as a barrier for purchasing behaviour due to the higher price in comparison to the conventional product. There were some studied showed that non-organic consumer claimed that organic food was expensive. If the organic was cheaper then they will consider to purchase it. On the other hand‚ the high income earner mentioned that the high price of organic was not an

When bismuth reacts with elements like air‚ water‚ acids‚ bases‚and halogens it drastically changes the form of the element. When Bismuth is heated and reacts with oxygen the air forms the the trioxide bismuth(III) oxide which creates a bluish white. When Bismuth is red heat‚ near melting point‚ and put into water‚ the water quickly cools down the Bismuth without drastically raising in temperature. When bismuth reacts

Amanda Stuart Fisher’s article “Bearing Witness” is a short reading explaining issues in our contemporary society. The reading discusses feminism frequently‚ which is the support for women’s rights to improve the equality of both sexes. A takeaway from the reading is how us as white men have a hard time fully understand someone else’s culture‚ and how we must take steps to mitigate this closed minded view. This relates with the reading that was titled “You Just Made The Blueprint To Suit Yourselves”
