The AP World History exam was first administered in 2002. The test underwent a major overhaul for the 2017 exam; however, due to the prodigious number of students that struggled with the free response section, the College Board decided to initiate yet another round of sweeping reform, to be put in effect in May 2018.
Oxygen difluoride is a chemical compound with the formula OF 2.As predicted by VSEPR theory, the molecule adopts a bent molecular geometry. [citation needed] It is a strong oxidizer and has attracted attention in rocketry for this reason. [5]
For example, the electron notation of phosphorus is 1s 2 2s 2 2p 6 3s 2 3p 3, while the noble gas notation is [Ne] 3s 2 3p 3. This more compact notation makes it easier to identify elements, and is shorter than writing out the full notation of atomic orbitals .
The following outline acts as an overview of and topical guide to chemistry: . Chemistry is the science of atomic matter (matter that is composed of chemical elements), especially its chemical reactions, but also including its properties, structure, composition, behavior, and changes as they relate to the chemical reactions.

Title page to the first edition. Intended for young beginners, for whom it is well adapted, as an introduction to the study of chemistry. [3]According to Frank Wilczek: . It is a wonderful laying-bare of surprising facts and intricate structure in a (superficially) familiar process — the burning of a candle.
The solution has 1 mole or 1 equiv Na +, 1 mole or 2 equiv Ca 2+, and 3 mole or 3 equiv Cl −. An earlier definition, used especially for chemical elements , holds that an equivalent is the amount of a substance that will react with 1 g (0.035 oz) of hydrogen , 8 g (0.28 oz) of oxygen , or 35.5 g (1.25 oz) of chlorine —or that will displace ...
