When HCl reacts with Na_2CO_3, what is created? More specifically, what are the crystals that remain? What happens when chlorine gas is bubbled through a solution of iron (II) salt in a boiling tube? Why was the reaction mixture from...
Suzuki reaction on 4-bromo-6-chloro-3-phenylpyridazine 179 shows that selectivity can also be achieved between a bromine and a chlorine atom and there is no requirement to have an iodine and chlorine atom on the skeleton (Equation 34) <2002SL223>. (34) While the introduction of aryl group...
Using the language of breaking and making bonds, explain how the formation of bubbles is often indicative of a chemical change. What evidence of a chemical reaction might you see when dropping an Alka-Seltzer tablet into a glass of water? What happens when chlorine...

(yellow green), chlorine water (pale yellow green) Red: CuO, Cu, Fe 2 + (SCN), methyl orange, purple litmus test solution in the acidic environment in the acidic environment, phenolphthalein, magenta in alkaline environment test solution, red phosphorus (dark red), Br2 (dark brown), Br2 ...
(A) Illustration of the basic steps. (B) Illustration of a batch-mode operation scheme in a cell with stationary electrodes and alternating circulation of the cold and hot electrolytes. In the first step ①, a cold (25°C) electrolyte (light grey) is circulated though the cell and the ...
According to energy-dispersive X-ray spectroscopy (EDS, Supplementary Table 1), the chlorine content was found to be smaller than 2%, and sometimes undetectable. This indicates a very small value of x in the end product. It is usually suspected that the formation and subsequent sublimation (or...

and with the use of the number of GA units calculated from charge neutrality, the average length of these chains and the average molecular weight were also determined. The average molecular weight of the partially methylated polygalacturonic acid used in the industrial-scale production of commercial ...
