In organic chemistry, ethers are a class of compounds that contain an ether group—a single oxygen atom bonded to two separate carbon atoms, each part of an organyl group (e.g., alkyl or aryl). They have the general formula R−O−R′, where R and R′ represent the organyl groups.
The Nokia 5.3 mostly received positive reviews. Radoslav Minkov of PhoneArena rated it at 7.8 out of 10 and praised the device's "smooth performance, impressive screen brightness and contrast, good portrait mode photos, and solid battery life" while criticizing the "low display resolution, unreliable fingerprint sensor and tinny speaker".
[9] [10] In 2009, Fifth Third completed the corporate spin-off of Fifth Third Processing Solutions, which was acquired by Worldpay, Inc. in 2012. [11] In May 2018, Fifth Third acquired MB Financial in a $4.7 billion transaction. [12] In August 2020, the bank signed a partnership with Trust & Will. [13]
In chemistry, dimerization is the process of joining two identical or similar molecular entities by bonds.The resulting bonds can be either strong or weak. Many symmetrical chemical species are described as dimers, even when the monomer is unknown or highly unstable.
Within a galaxy such as the Milky Way, particles have a much higher concentration, with the density of matter in the interstellar medium (ISM) ranging from 10 5 to 10 9 atoms/m 3. [113] The Sun is believed to be inside the Local Bubble , so the density in the solar neighborhood is only about 10 3 atoms/m 3 . [ 114 ]
The above norbornene system has S = 5, and Fawcett originally postulated that stability required S ≥ 9 in bicyclic systems [9] and S ≥ 11 in tricyclic systems. [10] For bicyclic systems examples now indicate a limit of S ≥ 7, [ 6 ] with several such compounds having been prepared. [ 11 ]
This is the first of five psalms (Psalms 5 - 9) all speaking of "the name of God", with nine verses speaking to various aspects, namely Ps 5:11, Ps 6:5, Ps 7:17, Ps 8:1, Ps 8:9, Ps 9:2, Ps 9:5 and Ps 9:10. [11] Various types of flow in the Book of Psalms are explored by various authors such as O. Palmer Robertson. [12]
Color pigments used on the warship Vasa, with white lead second from left, bottom shelf. White lead is the basic lead carbonate 2PbCO 3 ·Pb(OH) 2. [1] It is a complex salt, containing both carbonate and hydroxide ions.
