The manner in which chemistry is performed is changing, as well. Classical chemical batch reactions are being replaced by continuous flow reactions that offer better yield, higher quality and safer reactions. In
Ultrahigh dilutions Ultrahigh dilutions (UHD) are aqueous or aqueous-alcoholic solutions where a substance has been diluted through a special process in a 1023 times and higher.

A gastrointestinal diet was prescribed, and blood was submitted to a diagnostic laboratory for a CBC and serum biochemistry profile (ADVIA 120 Hematology System analyzer and Olympus AU640 Chemistry Analyzer). On the day of referral, the cat was icteric, depressed, and acutely anorexic. The ...
What is the molarity of a 500.0 ml solution containing 0.75 moles of solute? How much of a 3.5 M solution would be needed to make 300 mL of a 1.5 M solution via dilution? What volume (in mL) of a stock solution containing 6.00 M HNO_3(aq) is needed to prepare 1.50 L of 0.106 ...
The same is not true of the entropy; since entropy is a measure of the “dilution” of thermal energy, it follows that the less thermal energy available to spread through a system (that is, the lower the temperature), the smaller will be its entropy. In other words, as the absolute te...
In order to concentrate a solution, either more solute particles must be added or some solvent must be removed. If the solvent is nonvolatile, a solution may be concentrated by evaporating or boiling off solvent. Dilutionsare made by adding solvent to a more concentrated solution. It's common...
It is important to note that, accelerated by enhanced research in green chemistry, significant efforts are on-going in the use of earth-abundant metals such as iron to replace more toxic or expensive transition metals, thus somewhat mitigating one of the advantages of organocatalysis. Examples ...
Which of the following is not believed to have been a component of the early Earth's atmosphere? a. N2 (nitrogen gas) b. H2 (hydrogen gas) c. CO2 (carbon dioxide) d. O2 (oxygen gas) Explain the gas mixture used in single breath nitrogen washout and helium dilution. ...
