Question: How much heat is released when a mixture containing 23.0 g CS2 and 23.0 g Cl2 reacts by the following equation?
CS2(g) + 3Cl2(g) ---> S2Cl2(g) + CCl4(g) delta H= -230 kJ
Find the temperature at which ethanol boils on a day in the mountains when the barometric pressure is 547 mmHg. (Given: The heat of vaporization of ethanol is 39.3 kJ/mol; the normal boiling point of ethanol is 78.3°C.)
An evaluation of R was performed, following the procedure described in this module. The barometric pressure was 736 torr, the temperature was 295 K, and the volume of hydrogen gas collected was 35.6 mL. The calculated value of R was 82.1mL atm K-1..
