Question

The enthalpy of formation of gaseous N2O and No at 298k are 82 and 90 kJ/mol . The enthalpy of reaction N2O (g) + 1/2 O2= 2 NO -8kJ 98kJ -74kJ +8kJ Internal energy of a molecule is kinetic energy only Potential energy only Kinetic as well as potential unpredictable Hess's law is an application of 1st law of thermodynamics 2nd law of thermodynamics Entropy change del H = Del U + p del V Which of the following is not a state function ? T H q S The heat of neutralisation of aqueous hydrochloric acid by NaOH is x kcal/mol of HCl. The heat of neutralisation of per mol of acetic acid is 0.5 x kcal x kcal 2x kcal cannot be predicted The enthalpy change of reaction does not depend upon state of reactants and products nature of reactants and products various of intermediate reactions enthalpy of reactants and products The enthalpies of elements in their standard states are taken as zero. The enthalpy of formation of a compound is always negative is always positive may be positive or negative is never negative Bond dissociation enthalpy of H2,Cl2 and HCl are 434,242 and 431 kJ/mol respectively. Enthalpy of formation of HCl is -93kJ/mol 245kJ/mol 93 kJ/mol -245 kJ/mol The state of a gas can be described by quoting the relationship between pressure, volume, temperature temperature,amount, pressure amount, volume, temperature pressure, volume, temperature, amount What is the change in the energy of system if 500 cal of heat energy are added to a system and system does 350 cal of work on the surroundings ? -150 cal +150cal +850cal -850 cal For the reaction , NaCl(s) = Na+(g) + Cl- (g) identify the enthalpy involved in the above reaction enthalpy of hydration lattice enthalpy enthalpy of solution enthalpy of dissociation Calculate the difference between Cp and Cv for 10 moles of an ideal gas 83.14J 8.314 J 831.4 J 0.831J Which of the following properties is the measure of the degree of randomness or disorder in the system ? Entropy Enthalpy Internal Energy None of these In thermodynamics, a process is called reversible if surrounding and system change into each other there is no boundary between system and surroundings the surroundings are always in equilibrium with system the system changes into surroundings spontaneously The enthalpies of combustion of carbon and carbon monoxide are -393.5 and -283kJ/mol respectively .The enthalpy of formation of carbon monoxide per mol is -110.5 kJ -676.5 kJ +676.5kJ 110. 5kJ

Answer 1

Answer:

but the fact is the exact same as the one that I will be using animations for a while in a series of pictures and the same as I am watching it and I am not sure if I have to be honest with it or not to be a fan or a person with the other name
