Question
The heat released during a reaction between a compound and oxygen gas in the bomb surrounded by water in a bomb calorimeter is equivalent to the energy of combustion the enthalpy of combustion the energy of formation the enthalpy of formation. The relation between delta H_com and delta E_com for the combustion of one mole of cyclohexane C_6H_12(l) at temperature T is delta H_com = delta E_com - 2 RT delta H_com = delta E_com = 3 RT delta H_com = delta E_com - 4.5 RT delta E_com + 4.5 RT Vapor pressure of a liquid is defined as the pressure of vapor in equlibrium with the liquid phase in a closed system, in an open system in an isolated system in an adiabatic system. Which of the following is true for the vaporization of water at 1atm and 100 small circle C? delta H = 0 delta S = 0 delta G = 0 delta U = 0 A necessary condition for an electrochemical cell to be a galvanic cell at constant temperature and pressure is that it has a positive E positive delta H positive delta G positive delta S A certain amount of sodium thiosulfate was added in the reaction mixtures in the study of the kinetics of an iodine clock reaction. Its purpose was to catalyze the reaction reduce iodine oxidize iodide ion reduce the bromate ion.Explanation / Answer

Q1) The correct answer is Option B, Enthalpy of Combustion
Compound(A) + O2 ------ Products
Q2) C6H12(l) + 9.5O2(g) -------- 6CO2(g) + 7H2O(g)
The change in number of moles = 6 + 7 - 9 = 4.5
Hence Delta H = Delta E - 4.5RT, hence the correct answer is Option C
Q3) The correct answer is Option A (Closed system)
