Thames and Komos 3000 is the best 'adult' chemistry set. I have one myself and I'm 25. It gives you a nice starting point with the chemical assortment, and some glassware. Adding onto it with reflux glassware and more technical things makes it perfect for the home chemist. ...
Chemical kinetics is the division of physical chemistry that deals with the rates of a chemical reaction as well as the pathways through which a chemical reaction occurs. There are many factors which affect the rate of chemical reaction, catalyst is one of them....
What are the consequences of removing some of the phase transfer catalyst along with the hot reaction mixture after refluxing? What is the purpose of starch in the experiment: factors affecting reaction rate? Is there any evidence that the combination of Cu2+ and Fe3+...
35 parts of hexamethylene bis-dicyandiamide, 35 parts of p-chloroaniline hydrochloride and 250 parts of β-etoxyethanol are stirred together at 130- 140°C for 2 hours under reflux. The mixture is then cooled and filtered. The solid is washed with water and crystallised from 50% aqueous acet...
The high efficiency of these towers is because of the use of reflux. Reflux is basically the fraction of the condensed liquid in the tower. When this reflux falls down, it helps in lowering the temperature of the liquid moving in an upward direction, which further facilitate the condensation ...
When operating under pressure, a wider variety of reactions are conceivable, such as: Reactions at temperatures higher than reflux Gas-liquid reactions Gas-liquid-solid reactions The Vapourtec CSTR is developed with safety as a top priority. A burst disk and an optional safety screen are standard...
When these blockages prevent the urine from flowing to the bladder, it gets forced back up to the kidney in a process called vesicoureteral reflux. Other possible causes of hydronephrosis are tumors located on or near the ureter, an impassable kink in the ureter where it meets the bladder, ...
A reflux condenser is a piece of laboratory glassware that's used to cool vapors. It's made up of a glass tube encased in a glass...
Additional causes can include anxiety or depression, a stomach ulcer, gallbladder inflammation or pain, an intestinal disorder such as irritable bowel syndrome, a reflux disease in which stomach acid moves back up the esophagus, or even stomach cancer. Prevention of Dyspepsia Lesson Summary ...
