Fractional distillation of a mixture of 1: 1 ethyl acetate (b. p. 77.5°c) and 1-butanol (b. p. 117.0 °c) was performed, and differecns were collected. describe in detail, how many different fractions you will collect collect. pure or not? b. plot a graph for the fractional distillation data you will c. how can you use ir to check if the final fraction is pure or not?

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
