Thank you for all of your help! Yes, I hope the next set or problems actually relates to chemistry lol.

To be honest for the first two hints you have given me, I have no idea where to begin. :confused: My class is actually a chemistry computer class, and my instructor just gave us a problem set, and there is no section of the notes to reference to when attempting these problems, and we do not...

Homework Statement 1. A man bought a computer and when he booted it up he realized that the OS is not loading into RAM. Can you suggest what could be wrong with the computer? (Yes, the computer was plugged into the outlet and the power was turned on.) 2. Describe the process by which the...

Homework Statement I just purified alkaline phosphatase, and my calculated molecular weight is 100000 g/mol, while literature value is 89000 g/mol. According to how others in my lab did calculations, my calculations are performed correctly, so I am left to explain why my purification is...

First of all, after posting this, I changed the last few answers, with the corrected problems as: 1B 2A 3E 4c 5d 6E 7D 8D 9C 10E To answer your questions: For question 3, the leaf has photosynthetic pigments, producing sugars. The sugars are transferred from the leaf to the root...

Homework Statement I am assigning m/z peaks on a mass spectrum, and there are 3 peaks not on the chart given by the instructor, and I was wondering if anyone can help me determined their identities. The peaks I am unsure of are found at 95 m/z, 109 m/z, and 123 m/z; I already figured out the...

[SOLVED] Sites with IR, 1H NMR, 13C NMR, and mass spectroscopy? I was wondering if anyone knew where I can look at IR, 1H NMR, 13C NMR, and mass spectroscopy (sites or programs). I'd like to be able to input the name of an organic compound and be able to see these spectra. Thanks.

Homework Statement What is the solid that forms during the addition of phenyl magnesium bromide to methyl benzoate (step before triphenylmethanol)? Homework Equations See below. The Attempt at a Solution I know the structure of the product, but I don't know exactly how to name it. The...

Oh, the original equation is what the teacher gave us. I basically just had to plug everything in, but it didn't seem correct. So my answer is 0.078225 mol, and I convert that to grams? So 0.078225 mol x 136 g/mol = 10.6386 g? And yes, this is in the homework forum section.
