Essay Explain Which Steps In The Procedure To Reduce The Final Yield

Procedure: Measure the volume, mass, length and temperature of a variety of items. Create dilution of sugar water.

Compare the problem, solution, and technique in Buddhism with those of another eastern religion of your choice.

First students obtained 8 graduated cylinders and labeled them. Each one contained a different ratio of vinegar and water. These graduated cylinders with the liquid were weighed and recorded.Then, students obtained an Alka-Seltzer tablet and recorded its mass. Then one alka-seltzer tablet was dropped into each of the graduated cylinders. Students had to

3. What happens to the proof-rating of the brandy, as the distillation process continues? Why?

Selective reduction is normally a two-day medical process in which one or more fetuses are aborted while leaving other fetuses to develop. It is a routine procedure for In Vitro Fertilization (IVP). This process is a medical procedure whereby an egg is fertilized outside the body. About 10 percent of IVF procedures result in five or more fetuses. 20 percent are quadruplets, 60 percent triplets, and about 10 to 15 percent are twins. Most physicians who provide IVF will counsel 85 percent of their patients to accept a selective reduction that will reduce the pregnancy to twins. There are many difficult ethical questions raised when the method of IVP is used and can be considered moral and immoral. These moral questions also depend on the

Purpose: The purpose of this experiment is to observe a variety of chemical reactions and to identify patterns in the conversion of reactants into products.

The correct syringe is used to place 10 cm3 of the first glucose solution into the boiling tube.

When filling up the burette it is important that a funnel is used, however as the solution reaches the 0 mark it is ideal that the funnel be removed and a pipette used instead to reach the 0 mark, this is to achieve greater precision. During the experiment, it is important to swirl the flask continuously with one hand

alcohol (2-methyl-2-butanol, MW _ 88.2, d _ 0.805 g/mL) and 25 mL of concentrated hydrochloric acid (d _ 1.18 g/mL). Do not stopper the funnel. Gently swirl the mixture in the separatory funnel for about 1 minute. After this period of swirling, stopper the separatory funnel and carefully invert it. Without shaking the separatory funnel, immediately open

First, students set up one ice bath with TAP water, and a vacuum filtration apparatus. 2. 15mL of USP ethanol and 20mL of aqueous 10% NaOH was added into a 125mL Erlenmeyer Flask. 3. The mixture and flask was swirled and left to cool in ice bath until the temperature of the mixture was 20˚C. 4.

During each phase of the experiment, an intermediate product was obtained and through transfer to and from multiple round bottom flasks, Erlenmeyer flask, and funneling, majority of the product was lost. Additionally, a small percent of the product would be lost to the aqueous layer. Minimizing intermediate product transfer and an alternate funnel method would have drastically minimized the considerable amount of product

Then use a scoopula to scratch the bottom of the reach beaker to help the alum crystals maintain shape. Once the reaction beaker is done forming the alum crystals, sterilize and put together the vacuum filtration apparatus. Then transfer the alum crystals onto a new filter paper. After that, the beaker is consumed twice with 10mL of 50 percent of the ethanol solution. The alum crystals on the filter paper are filled with the 10mL of ethanol as well as using the vacuum to dry the alum crystals.

A 10 mL round-bottom flask was weighed both before and after approximately 1.5 mL of the given alcohol, 4-methyl-2-pentanol, was added. 3 mL of glacial acetic acid, one boiling chip, and 2-3 drops of concentrated sulfuric acid were added to the flask in that order. The reflux apparatus was assembled, the

The results that were revealed were thought to be accurate and reliable as many factors were controlled to enable the best quality. The results that a constant rise in the combustion occurred as each alcohol’s carbon chain increased with one exception indicates that the reliability of this experiment has to be examined. With such a high percentage error from these results means they cant be definitive. Also only three trials were conducted on the five different alcohols. If the experiment were to be conducted again I would conduct five trials on each alcohol to get a better average.

Step 1 and 2 was repeated by using distilled water by replacing the test solution.
