If 164.8 g of iodine monobromide is combined with 62.4 g of ammonia, determine the amount of excess reactant that remains after the reaction is completed and the percentage yield of nitrogen triiodide if 96.4 is produced?

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)]

Anyone who's in connections academy chemistry b have the factors that affect the rate of a reaction portfolio already done?
