An insulated piston-cylinder device contains 1 L of saturated liquid water at pressure of 150 kPa. An electric resistance heater
inside the cylinder is now turned on, and 2869.47 kJ of heat is transferred to the water. The inside H2O pressure maintains constant at 150 kPa during the process. Determine: the entropy change of the water during this heating process, in kJ/K.
1 answer:
Answer:
Explanation:
In this problem,
we will determine the enthalpy at the end of heat input and we get the condition is the super heated state.
so the entropy change will be due to latent heat at 150 kPa and also due to temperature change at the super heated state.
All the temperature, enthalpy is evaluated with the help of the steam table.
mass is calculated with the help of a specific volume at initial condition.

Mixing of pure orbitals having nearly equal energy to form equal number of completely new orbitals is said to be hybridization.
For the compound, the electronic configuration of the atoms, carbon and hydrogen are:
Carbon (atomic number=6): In ground state=
In excited state:
Hydrogen (atomic number=1):
All the bonds in the compound is single bond(-bond) that is they are formed by head on collision of the orbitals.
The structure of the compound is shown in the image.
The Carbon-Hydrogen bond is formed by overlapping of s-orbital of hydrogen to p-orbital of carbon.
In order to complete the octet the required number of electrons for carbon is 4 and for hydrogen is 1. So, the electron in of hydrogen will overlap to the 2p^{3}-orbital of carbon.
Thus, the hybridization of Hydrogen is -hybridization and the hybridization of Carbon is
-hybridization.
The hybridization of each atom is shown in the image.
