Question- When crystalline solid barium hydroxide octahydrate and crystalline solid ammonium nitrate are mixed in a beaker at room temperature, a spontaneous reaction occurs. The temperature of the beaker contents rapidly falls below zero degrees Celsius. Use this information to decide whether the reaction is exothermic or endothermic and what the signs of delta H and delta S are.
