    Can Spectroscopy Be Used to Test Arsenic in Applesauce?

    Ok I'm testing for arsenic in applesauce. I was thinking of using SERS since that is the lab I'm working in right now. To reduce the noise, I thought I could make some homemade applesauce and subtract the spectra from the store bought applesauce. I'm not sure about the separation technique...

    Can Spectroscopy Be Used to Test Arsenic in Applesauce?

    I was thinking of preparing applesauce for some type of spectroscopy( ex: Raman). I was thinking of testing it for arsenic. Does anyone have any idea what applesauce would dissolve in ( I realize this is more of a biology question). thanks

    Enthelpy and Heat State Functions

    I'm sure this topic has been asked before so I'd be happy if you'd just direct me to the thread. I know U+PV=H and if the only work done is PV work then H=q-P∆V+P∆V=q. And I know that pressure must be constant. I also know that a state function is a function where the value of the function...

    Free Energy Thought Experiment Question

    Ok Thanks. Yeah I meant 1*10^-4 for the force needed to break it. I don't know about elastic properties so I just invented a number. But you answered my question. I guess events in the future can't affect the past.

    Free Energy Thought Experiment Question

    I have a thought experiment I don't understand. Imagine there's a grain of salt that weighs 5 mg and it's 1mm above above a pool of water and it's on a very thing piece of flimsy material that takes about 1*10^-5 Newtons of force to break. Using Newton's 2nd law, I get the grain of salt is...

    Synthesis of polymers containing biarenes

    I am a high school chemistry AP student. In class, my teacher told us about how benzene's delocalized ∏ electrons can donate to a metal but it is not a strong bond. I wanted to know if it was possible to make a coordination compound that was also a polymer by using a biarene ligand, one end...
