Urea is an organic compound widely used as a fertilizer. its solubility in water allows it to be made into aqueous fertilizer solutions and applied to crops in a spray. what is the maximum theoretical number of water molecules that one urea molecule can hydrogen bond with? ignore shape for the purposes of this answer. urea could theoretically form hydrogen bonds with this number of water molecules. note, however, that the size and shape of a molecule may limit the number of hydrogen bonds formed by one urea molecule.

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 23.5c. 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)]
