CaCO3(s)⟶CaO(s)+CO2(g)CaCO3(s)⟶CaO(s)+CO2(g) Express your answer as a chemical equation. Identify all of the phases in your answer. Keep the order of compounds as in the original equation.

The figures below are of temperature monitos with blue fluid in which a tube (that was also been filled with the blue fluid has been inverted and placed in the beaker (open on the end that's submerged in the blue fluid). As the temperature is raised on the beaker/tube system that level of blue fluid in the tube will transition A completely full B partially full, C at the same level of blue fluid in the beaker. 20 °C 30° C 55 °C A B C When does the temperature of the fluid represent it's boiling point?

Determine the vapor pressure of a liquid in kPa at 383 K. The enthalpy change is 29 kJ/mol. At 310 K, its vapor pressure is 19 kPa. Use this information to estimate the pressure of the vapor at the first temperature. Hint: You must put the enthalpy value into J/mol to cancel units with R. Round your answer so that it has 1 decimal place. R= 8.314 J/(mol*K) Your Answer:
