Organic Chemistry-Kp value Suppose, you have 35 mg of benzoic acid dissolved in 7 ml of dichloromethane. The resulting organic soln is then extracted w/ 12 ml of water. the dichloromethane layer is now 31 mg of benzoic acid. What is the partition Coefficient (Kp) of benzoic acid in dichloromethane/water? I think the equation is…
physical chemistry in Atkins 9thE question 8.31 when beta-carotene is oxidised in vivo, it breaks in half and forms two molecules of retinal (vitamin A). which is a precurser to the pigment in the retina responsible for vision. The conjugated system of retinal consist of 11 C and one O atom. in the ground state […]
please help me solve the problem The reaction is second order in and has a rate constant of 0.0123 at 25.0 . A reaction vessel initially contains 250.0 of 0.133 which is allowed to react to form the gaseous product. The product is collected over water at 25.0 . How much time is required to […]
cis-1, 2-dichloroethene lewis structure with vectors, charges, % ionic character, and % covalent I think the formula for this is C2 H2 Cl2, but the name is completely foreign to me.. my teacher has had us do substances like molecular oxygen and potassium cyanide, but I am completely lost on this on
Lewis Structure for trans-1, 2-dichloroethene—- C2 H2 Cl2 I need the Lewis dot, and Lewis structure to include vectors, charges and %IC, %CC
second order half life 2. The following second-order reaction occurs at room temperature: 2ClO (g) ? Cl2 (g) + O2 (g) The following data was collected in the laboratory: Time (milliseconds, ms) [ClO] (ÂľM) 12.0 8.49 96.0 7.10 224 5.79 320 5.20 400 4.47 ⢠Use this data to determine the reaction order and calculate […]
This is inorganic chemistry problame, please help me out ( show your work please) 3) Europium is a lanthanide metal that is abundant ( for a lanthanide) and that is under intense investigation for certain device uses. A galvanic cell uses the Eu^3+/Eu^2+ redox couple. The counter-reaction is the dissolution of a solid titanium electrode […]
Determining Half-Life Here is the problem. I think my first step is determining the rate constant. How do I do it from the information provided? 2. The first order reaction A —> Products has a half-life of 46.2 minutes at 25oC and 2.6 minutes at 102oC. a) Calculate the activation energy for this reaction. b) […]
Concentrations and pH in Chem 2 WILL RATE HIGH What are the […] (concentrations) and pH for .12 NH4Cl? Ka of NH4+ is 5.6×10-10 What is: [NH4+] [H3O+] [NH3] [OH–] [Cl–] pH
Williamson Ether Synthesis of Phenacetin Draw and describe the mechanism of reaction (using arrows for electron pushing), is it SN1, SN2, E1 or E2? Does the acetaminophen have to deprotonate to the phenolate before reacting?
