    What is the relationship between particle velocity and sound waves in air?

    I have an air molecule moving because of a sound wave. f of sound wave = 500 Hz wavelength of sound wave = 0.68 m How fast is the air molecule moving in its equilibrium position? Is it in equilibrium at V max? Would this be where the position = 0?

    Synthesize 3-Methyl-3-Hexanol from Acetylene: Instructions & Tips

    I need to figure out how to synthesize 3-methyl-3-hexanol from acetylene. So, there is a methyl and an OH on the third carbon. I am learning all the different reactions, but I am having a hard time figuring out where the triple bond is and how to do it with the methyl group on there. Is there...

    Sublimation of MP & VP: Separating Compounds

    I am wondering if I can separate these two compounds: Y: M.P.=170 degrees C - Vapor pressure at its MP = 0.05 torr Z: M.P.=170 degrees C - Vapor pressure at its MP = 540 torr I think having a huge difference in vapor pressures is good. I am kind of confused about this process.

    I am wondering if this would work:I need to sublimate compound 1

    I am wondering if this would work: I need to sublimate compound 1 (mp 175-177 C) from compound 2 (206-208 C) at 120 C at atmospheric pressure. Crystals are found and the solids melting point is 150-160 C. Could anyone help me? I am not completely clear.

    Bromination of an alkene using isopropanol

    What would be the product if I carried out a bromination of an alkene using isopropanol as the solvent?

    What Are the Products of Brominating trans- and cis-1,2-Diphenylethene?

    I am asked for the "actual products" of reacting Br(2) with: trans-1,2-diphenylethene and cis-1,2-diphenylethene I know their structures. And I know that each Br will attach to each side of the double bond. Are there three products for each? ...with the products being isomers?

    Ring Expansion of 1,3-Methylcyclopentene with H-Br

    Okay. Thanks for your help!

    Ring Expansion of 1,3-Methylcyclopentene with H-Br

    It's not just one product? Is the product then a 5-membered ring with a methyl and Br on 1 and the other methyl on 3? We are not doing stereochem yet with these. Wouldn't the most stable and therefore major product be what I came up with?

    Ring Expansion of 1,3-Methylcyclopentene with H-Br

    Would the carbocation need to be on a C other than the C's that make up the ring? It would need to be on the methyl? Could do a hydride shift to achieve this. But that isn't favorable because you would be shifting from a tertiary to a primary. Am I correct? So no ring expansion?

    Ring Expansion of 1,3-Methylcyclopentene with H-Br

    The carbocation is most stable when it is on a tertiary carbon, so if possible, it will shift to be more stable. So the H would go on the secondary carbon, and the tertiary carbon is the carbocation. So, the Br would be on the same C as the methyl. I think this is correct, but what about a...

    Ring Expansion of 1,3-Methylcyclopentene with H-Br

    Sorry about the naming. I am just starting organic chemistry. I will try to explain the structure... A 5-membered ring with one double bond and two methyl groups off of it. Say the double bond is between 1 and 2. Number around the ring clockwise 1-5. One methyl is on 1, and the other methyl is...

    Ring Expansion of 1,3-Methylcyclopentene with H-Br

    I need to react 1,3-methylcyclopentene with H-Br. Do I do a ring expansion here? What I came up with is 1-bromo-3-methylcyclohexane. Am I completely off? Is there just one major product? I would appreciate the help!

    Solving the Nernst Equation for Zn^2+ Concentration

    I built a cell with one side containing the solution 0.10 M CuSO4 with Cu(s) in it. The other side has 1 M NH3 and 0.05 M ZnSO4 with Zn(s) in it. The measured cell potential was 1.31. I am using the Nernst equation. I need to find the concentration of Zn^2+. E=E"-(0.059/2)logQ 1.31 =...

    Finding the concentration in a solution

    It is a total of 50 ml. Water is added to the solution until it is 50 ml. 0.080 M Cu(NO3)2 = 0.00016 moles in 2 ml
