  1. Consider the following reduction potentials: Cu2+ + 2e- --> Cu E° = +0.34 V Pb2+ + 2e- --> Pb E° = -0.13 For a galvanic cell employing the Cu, Cu2+, Pb, Pb2+ couples, calculate the maximum amount of work (in kJ) that would accompany the reaction of one mole of lead under standard conditions. Hmmmmm help plz
  2. The question simply is, which could be reduced by Cu? Sn2+ (superscript 2+) Ag+ (superscript +) Zn2+ (superscript 2+) How do i figure this out? ...by using some sort of database? I know copper will spontaneously reduce Ag+ Not sure about the other 2.
  3. stop confusing me i need answers!!
  4. esters can undergo reduction......i found the answer to that question anyway. any thoughts on the others?
  5. Forget that last question, any help on the others would be very much appreciated.
  6. Would LiAlH4 be a viable reagent for converting methyl propanoate to 1-propanol + methanol? Other possible reagents i can choose from are: NaBH4 Fe/HCL PCC Sn/HCL ....I would think LiALH4 would be the preferred reagent because i read this on the internet "LiAlH4 is a powerful reducing agent which reduces carboxylic acids to primary alcohols in good yields" I know cold dilute sodium bicarbonate could be used for a chemical test to distinguish between benzoic acid and benzamide. Could cold dilute sodium hydroxide be used also? This other question in the textbook has got me stumped too. When treated with sodium iodide, a solution of (S)-2-iodooctane in acetone.....(more than 1 correct answer) 1. does not react 2. loses its optical activity 3. gives both ® - and (S) -2-iodooctane 4. is converted to ® -2-iodooctane I'm really struggling with this question and don't know where to start. Also, what would be the name for the compound C7H12 that reacts with ozone followed by hydrogen peroxide to give heptane-2,6-dione as the only organic product? Thanks.
