Consider the thermal decomposition of CaCO3: CaCO3
(s) CaO(s) + CO2
(g)
The equilibrium vapor pressures of CO2 are 22.6 mmHg at 700 oC and 1829 mmHg at
950 oC. Calculate the standard enthalpy of the reaction.

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.
