  • B.A. in Chemistry with an M.B.A.?

    I currently have a B.A. in chemistry and am currently working as an chemist in pharmaceutical development. I always intended on getting my master's degree, but I'm debating whether to continue in chemistry or whether I should get an MBA. I don't see myself working in a lab forever and would love to transition into the corporate area of pharmaceuticals. Is this a sensible choice?

  • What does my dream mean?

    Last night I had an apocalyptic type of dream where a lot of people were taken in the rapture. I was left behind with one of my friends and we were on the run because there were people after us. We stole a car and went to a hotel, but when we got there our room had been broken into. We grabbed as many things as we could and while I was packing my suitcase I got a call from my mom, but she called to tell me that both her and my dad were dead. In the dream I was distraught, but she kept trying to calm me down. She said she just wanted to let me know that everything would be alright and to say goodbye. After this I woke up and was very scared and extremely sad. Help! What does this mean???

  • If ΔG<0, what does this tell you about the reaction? If ΔS>0, what does this tell you about the reaction?

    If ΔG<0, what does this tell you about the reaction? If ΔS>0, what does this tell you about the reaction? If we do an experiment in a Styrofoam cup and start with 50 g of methanol at 25.0C and mix 50 g of acetonitrile at 25.0C to determine the heat of mixing, will we get ΔE or ΔH directly from the experiment?
