The enol carbon or ∝-carbon nucleophile attacks at molecular bromine in the acid-catalyzed α-bromination of a ketone
Treatment of ketones with bromine in the presence of acid will results in formation of a new C-Br bond at the alpha position. The purpose of the acid is to catalysed formation of the enol from ketone , which is active nucleophile in the reaction. This reaction is called haloform reaction which is used to identify the methyl substituted ketone in the presence of aldehyde.

Answer:
Acidic proteins are proteins that move faster than serum albumin on zone electrophoresis (starch or acrylamide gel) and which bind most strongly to the basic ion exchangers used in protein chromatography.
Basic protein is a late gene product associated with the viral DNA within the nucleocapsid. The harnessing of this promoter allows the expression of foreign genes at earlier times than those using the very late phase promoters of the polyhedron and p10 genes.
Calculate the pOH first :
pOH =14-8.57=5.43
(OH)=10^-5.47
(OH)=3.72 x 10^-6 mol/L
Answer:
a. When one substance transfers electrons to another.
Explanation:
The redox reaction occurs when one substance oxides and other reduces. To oxide, the compound must lose electrons, and to reduce, it must gain electrons. So, when it's observed that electrons are being transferred, we can tell that a redox reaction is happening.
The oxygen is a good oxidation agent and intends to reduce, but the combustion reaction, for example, involves oxygen and it's not a redox reaction. The reaction between a metal and a nonmetal not necessarily will be a redox reaction.
Adding energy can put the reaction in a state of equilibrium because more energy allows the reverse reaction, which is endothermic, to occur along with the forward reaction
