Astudent is preparing to perform a series of calorimetry experiments. she first wishes to determine the calorimeter constant (ccal) for her coffee cup calorimeter. she pours a 50.0 ml sample of water at 345 k into the calorimeter containing a 50.0 ml sample of water at 298 k. she carefully records the final temperature of the water as 317 k. what is the value of ccal for the calorimeter

is there any options? maybe im just not seeing them but i need the options to

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
