What is the purpose of the return sludge step in the activated sludge process? What are some of the uses of diamond? What is the purpose of centrifugation in protien purification? What advantage does refluxing a compound have that boiling it on a hot plate does not?
Reflux, in organic chemistry, is a process that involves the heating of a chemical reaction for some time. At the same time, the vapor produced from...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your...
they are a low level toxin. The purpose of lectins is to discourage other animals from eating that life form. By triggering a negative reaction in the predator, that life form is then viewed as an undesirable food source. Hence, aiding its future survival. ...
Finally, pH is important in chemistry, agriculture, medicine, oceanography, engineering, biology, and water purification. Why Do We Test our Water for Ph? Again, pH is a numerical value used to determine if the water is acidic. The water quality regulations specify that the tap water ...
aAmphetamine can be obtained in a 30% yield in a one step synthesis by refluxing phenylacetone in ethanol with ammonia, aluminium grit, and a small quantity of mercuric chloride. In the course of our educational program in pharmacochemistry, literature research was performed on the synthesis of...
A reflux condenser is a laboratory glassware that is used to cool vapors. It consists of a glass tube encased in a glass cylinder. The tube connects the fractioning column with a flask and carries hot vapors produced from heating. Water is contained the glass cylinder; the water is pumped ...
Six of these 32 patients with refluxing stumps (19%), all girls, became symptomatic during followup. Symptomatic UTIs recurred in these 6 patients an average of 12 times per year (range 8 to 21), which significantly decreased after distal ureterectomy. If surgery is indicated in patients ...
And all of that makes being bipolar look like a walk in the park. Because hell, it’s just a handful of manic days where you have a really good time being yourself and everyone thinks you’re amazing and a long string of depression filling up the space in between. The ADHD, is simpl...
