Given the balanced thermochemical equation, 2 H2O(1) + H2(g) + O2 (8) AHrån = +572 kJ determine the heat associated with the reaction (grxn) when5.6 moles of O 2(g) are produced. Round and report your answer without any decimal place.

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)]
