What is Br2's boiling point? Bromine Bromine is the one halogen that is a liquid at room temperature and atmospheric pressure. Since it's a halogen, it's very reactive and is more stable in molecular form. This is why bromine is written as Br2. Answer and Explanation: Become a Study...
At room temperature, tungsten can be quickly dissolved in a mixed acid of hydrofluoric acid and concentrated nitric acid, but it has no effect in alkaline solutions. In the presence of air, molten alkali can oxidize tungsten into tungstate. In the presence of oxidants (NaNO3, NaNO2, KClO3, ...
4 decomposes at room temperature and reacts with t-BuNH2 to give, (CO)5MOP(NH-t-BU)2NH2 (6). 1 and HI form (CO)5MoPI3. 3 can also be prepared from 2 with HBr, 4 from 2 and 3 with HBr and HI, respectively. The reactions of 2-4 with NR3 produce polymers, whereas the ...
(b) 2-[(5-Methyl-3-isoxazolyl)amino]methyl phenol (5a–g): Sodium borohydride (2 mmol) was added to solution of the compound 4 (1 mmol) in methanol (10 ml) and mixture was stirred for 30 min at room temperature. The reaction is monitored by TLC. The solid separated on pouring th...
For immunostaining, cells were incubated for 2 h at room temperature with 20 μg/mL rabbit anti-KCa1.1 antibody (Sigma) in blocking solution. After three washes with PBS, cells were incubated for 1 h at room temperature with an AlexaFluor 488-labeled goat anti-rabbit antibody (Life ...
Which of these does not describe a metal at room temperature? a. bendable b. gas c. liquid d. solid e. shiny Give the normal state (solid, liquid, or gas) of tungsten. Which of the following elements have the same physical state (solid, liquid, ga...

The mixture was stirred at room temperature for 2 h. The product was isolated by column chromatography on a silica gel column eluting with hexane:CHCl3:EtOAc:EtOH at 10:8:4:4 (120 mg solid, 49%). 62 (PU24I): 2-Iodo-9-pent-4-ynyl-8-(3,4,5-trimethoxy-benzyl)-9H-purin-6-...
An efficient and simple procedure has been developed for the oxidation of 1,3,5-trisubstituted 4,5-dihydro-1H-pyrazoles and -isoxazoles to their corresponding aromatic derivatives promoted by bis-bromine-1,4-diazabicyclo[2.2.2]octane complex (DABCO-Br2) in acetic acid at room temperature. The...
