A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.

Less of the "full breadth" of most traditional engineering undergraduate curricula will be captured with this approach - such as the broad math and science foundation spanning chemistry, physics, mechanics (i.e. statics and dynamics), materials science, computer science, electronics/circuits, engineering design, and the standard range of ...
Atmospheric pressure chemical ionization chamber cross section. Atmospheric pressure chemical ionization (APCI) is an ionization method used in mass spectrometry which utilizes gas-phase ion-molecule reactions at atmospheric pressure (10 5 Pa), [1] [2] commonly coupled with high-performance liquid chromatography (HPLC). [3]
There are less than 20 days until Christmas, but St. Nicholas comes on Dec. 6. Here's what to know about the holiday.
Bill Murray appeared on Travis and Jason Kelce’s “New Heights” podcast (via The Daily Beast) and defended the current cast of “Saturday Night Live” from critics who say the show has ...
At around 7.20 p.m. local time, Sanjari posted a photo from atop a high structure, with the caption: “7 PM, Hafez Bridge, Charsou.” Charsou Bazaar is a commercial building in downtown Tehran.
For example, if a compound travels 9.9 cm and the solvent front travels 12.7 cm, the R ƒ value = (9.9/12.7) = 0.779 or 0.78. R ƒ value depends on temperature and the solvent used in experiment, so several solvents offer several R ƒ values for the same mixture of compound. A solvent in chromatography is the liquid the paper is placed in, and ...
