Answer:
a. T and P remain the same (T=298 K and P=1 bar)
b. 11.23J/K
Explanation:
a. Since the mixing process of an idea gas doesn't present a change in the enthalpy, we could state that no change in neither temperature and pressure are given.
b. It is not necessary to know enthalpy data, the following formula is enough to compute the entropy change:
Δ![S_{mix}=-n_{N_2}R ln(x_{N_2})-n_{O_2}R ln(x_{O_2})](https://tex.z-dn.net/?f=S_%7Bmix%7D%3D-n_%7BN_2%7DR%20ln%28x_%7BN_2%7D%29-n_%7BO_2%7DR%20ln%28x_%7BO_2%7D%29)
Thus, the molar fractions are equal to 0.5, and the result yields:
Δ![S_{mix}=-(1mol)[(8.314J/(mol*K)]ln(0.5)-(1mol)[(8.314J/(mol*K)]ln(0.5)](https://tex.z-dn.net/?f=S_%7Bmix%7D%3D-%281mol%29%5B%288.314J%2F%28mol%2AK%29%5Dln%280.5%29-%281mol%29%5B%288.314J%2F%28mol%2AK%29%5Dln%280.5%29)
Δ![S_{mix}=11.23J/K](https://tex.z-dn.net/?f=S_%7Bmix%7D%3D11.23J%2FK)

Answer:
Graphite is insoluble in water and organic solvents - for the same reason that diamond is insoluble. Attractions between solvent molecules and carbon atoms will never be strong enough to overcome the strong covalent bonds in graphite. conducts electricity.

Energy is the ability to do WORK or cause CHANGE it’s measure in JOULES and is found in many different FORMS. Energy can be classified as KINETIC or POTENTIAL energy. (I’m pretty sure that’s correct, hope that helps!)
