The 2014 AP Chemistry exam was the first administration of a redesigned test as a result of a redesigning of the AP Chemistry course. The exam format is now different from the previous years, with 60 multiple choice questions (now with only four answer choices per question), 3 long free response questions, and 4 short free response questions.
Compound Interest is a website launched in 2013 by Andy Brunning with infographics on everyday chemistry. [1] [2] The infographics describe, for example, how chemicals found in food and nature give them smell, taste, and color. [3] The website has a monthly collaboration with the American Chemical Society. [4]
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.
The predecessor to the current AP Capstone program, the AP/Cambridge Capstone Program, was initially offered in 17 high schools worldwide. With the launch of the full AP Capstone by the College Board in fall 2014, the program has expanded to now being offered in 1100 schools. [2] Over 100 colleges and universities support the AP Capstone ...
Ammonium perchlorate ("AP") is an inorganic compound with the formula NH 4 ClO 4.It is a colorless or white solid that is soluble in water. It is a powerful oxidizer.Combined with a fuel, it can be used as a rocket propellant called ammonium perchlorate composite propellant.
The relative activity of a species i, denoted a i, is defined [4] [5] as: = where μ i is the (molar) chemical potential of the species i under the conditions of interest, μ o i is the (molar) chemical potential of that species under some defined set of standard conditions, R is the gas constant, T is the thermodynamic temperature and e is the exponential constant.
The world watched as A$AP Rocky flung himself into his partner Rihanna’s arms after he was acquitted Tuesday and now she has shared her joy.
The Green Book is a direct successor of the Manual of Symbols and Terminology for Physicochemical Quantities and Units, originally prepared for publication on behalf of IUPAC's Physical Chemistry Division by M. L. McGlashen in 1969. A full history of the Green Book's various editions is provided in the historical introduction to the third edition.
