The solubility of Xe in water at 1 atm pressure and 20 °C is approximately 5 X 10-3 M .Compare this with the solubilities of Ar and Kr in water (Table) and explain what properties of the rare gas atoms account for the variation in solubility.
Please draw a detailed, arrow-pushing mechanism for the addition of HBr to trans-2-butene. 4. Please draw a potential energy diagram for this reaction
Metabolic reactions are regulated by a variety of regulatory mechanisms. Mention and discuss five mechanisms. Give clear examples of each.
The first-order rate constant for the reaction of methyl chloride (CH3Cl) with water to produce methanol (CH3OH) and hydrochloric acid (HCl) is 3.32 10-10s-1 at 25°C.
