You are doing research and the reaction you need to run is limited by the amount of alcohol you have. 3,3-diethyl-2-pentanol will be dehydrated to form alkenes. Give balanced equation and calculate the theoretical yield if you have 5.00mL of alcohol available.
A student made an acetic/acetate buffer by mixing 4.665 g of sodium acetate into 600.00 mL of a 0.0242 M acetic acid solution. What would the pH of the solution be as the result of the addition of 0.0050 mols of hydrochloric acid to the buffer
The endpoint corresponds to the equivalence point. D. At the equivalence point the amount of reagent added does not yet equal to the amount of analyte present
