Calculate the enthalpy change for the reaction CaCO3(g)→CaO(s)+CO2(g) , from the following equations: 2Ca(s)+O2(g)→2CaO(s) ΔH=−1270kJ 2Ca(s)+2C(s)+3O2(g)→2CaCO3(s) ΔH=−2414kJ C(s)+O2(g)→CO2(g) ΔH=−394kJ

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
