What is the heat of formation of MgO?
The heat of formation of MgO is -601.6 kJ/mol. This value represents the heat released or absorbed when 1 mole of magnesium oxide is formed from its elements in their standard states.
What is calorific value of benzoic acid?
The calorific value of benzoic acid is approximately 26.4 kJ/g when burned in a bomb calorimeter. This value represents the amount of energy released when the substance is completely combusted.
Which of the following values represents the molar mass of methane?
The molar mass of methane (CH4) is approximately 16 g/mol.
Standard enthalpy of combustion of ethanol?
The standard enthalpy of combustion of ethanol, C2H5OH, is approximately -1367 kJ/mol. This value represents the heat released when one mole of ethanol is completely burned in excess oxygen to form carbon dioxide and water.
What is the first ionization energy of tellurium?
The first ionization energy of tellurium is 9.01 electron volts (eV) or 869 kJ/mol. This energy represents the amount of energy required to remove the outermost electron from a neutral atom of tellurium to form a positively charged ion.
What is the value represents the molar mass of methane?
The molar mass of methane (CH4) is approximately 16.04 g/mol.
What is the accepted value for the heat of solution NH4Cl?
The accepted value for the heat of solution of NH4Cl (ammonium chloride) is approximately +14.8 kJ/mol. This value represents the energy released or absorbed when one mole of NH4Cl dissolves in water at standard conditions.
What is the heat of fusion of neon?
The heat of fusion of neon is 0.335 kJ/mol. This value represents the amount of energy required to change neon from a solid to a liquid at its melting point.
What is the heat of formation of MgO?
The heat of formation of MgO is -601.6 kJ/mol. This value represents the heat released or absorbed when 1 mole of magnesium oxide is formed from its elements in their standard states.
The ionization energy for sodium is 496 kJmol The electron affinity for chlorine is -349 kJmol what is the enthalpy?
The enthalpy change for forming sodium chloride from its elements can be calculated using the equation: Enthalpy change = Ionization energy of sodium + Electron affinity of chlorine. Plugging in the values, we get: 496 kJ/mol + (-349 kJ/mol) = 147 kJ/mol. Therefore, the enthalpy change for forming sodium chloride is 147 kJ/mol.
What is the lattice energy for potassium bromide?
The lattice energy for KCl is 715 kJ mol-1.
What is the heat of formation of NaCl?
The standard enthalpy of formation for sodium chloride is -411,12 kJ/mol.
How can the conversion from mol/kgm2 to mol/gcm2 be calculated?
To convert from mol/kgm2 to mol/gcm2, you can use the conversion factor 1 kg 1000 g and 1 m2 10000 cm2. Multiply the original value by 1000 and divide by 10000 to get the equivalent value in mol/gcm2.
