Sodium carbonate (na2co3) reacts with acetic acid (ch3cooh) to form sodium acetate (nach3coo).
carbon dioxide (co2), and water (h2o) a chemist cames out this reaction in a bomb calorimeter. the
reaction causes the temperature of a bomb calorimeter to decrease by 0.985 k. the calorimeter has a
mass of 1.500 kg and a specific heat of 2.52 j/g-k. what reaction is this ?
