Sodium carbonate (Na2CO3) reacts with acetic acid (CH3COOH) to form sodium acetate (NaCHgCOO), carbon dioxide (CO2), and water (H2O). A chemist carries 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 is the heat of reaction for this system?
kJ

Nitric acid can be formed in two steps from the atmospheric gases nitrogen and oxygen, plus hydrogen prepared by reforming natural gas. in the first step, nitrogen and hydrogen react to form ammonia: (g) (g) (g) in the second step, ammonia and oxygen react to form nitric acid and water: (g) (g) (g) (g) calculate the net change in enthalpy for the formation of one mole of nitric acid from nitrogen, hydrogen and oxygen from these reactions. round your answer to the nearest .
