Given the balanced equation for the oxidation of ethanol, c2h5oh, by potassium dichromate:
3 c2h5oh + 2 k2cr2o7 + 16 hcl > 3 c2h4o2 + 4 crcl3 + 4 kcl + 11 h2o
calculate the volume of a 0.600m k2cr2o7 solution needed to generate 0.1665 moles of c2h4o2 from a solution containing excess ethanol and hcl.
a) 278 ml b) 185 ml c) 111 ml d) 6.60 ml

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)]
