The fizz produced when an alka-seltzer® tablet is dissolved in water is due to the reaction between sodium bicarbonate (nahco3) and citric acid (h3c6h5o7): 3nahco3(aq)+h3c6h5o7(aq)→3co2(g)+3h 2o(l)+na3c6h5o7(aq) in a certain experiment 1.50 g of sodium bicarbonate and 1.50 g of citric acid are allowed to react.

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)]
