Answer:

internal energy E 3716.35 j

cv = 12.47 J/K

S = 12.47 J/K

A =  0.29 J

\mu =3716.35 J/mole

Explanation:

given data:

Kr  atomic number = 36

degree of freedom = 3

1) internal energy E = \frac{f}{2} n R T

                                = \frac{3}{2} *1*8.314*298 = 3716.35 j

2) cv = \frac{E}{T}

         = \frac{3716.35}{298} = 12.47 J/K

3) S = cv =\frac{E}{T} = 12.47 J/K

4) A, Halmholtz free energy = E -TS = 37146.35 - 12.47*298 = 0.29 J

5)chemcial potential \mu = \frac{energy}{mole} = 3716.35 J/mole

Express your emotions on how bad fraud and corruption and how they must be avoided
Bas_tet [7]

Fraud is dishonest activity causing actual or potential financial loss to any person or entity including theft of personal identity, moneys or other property by employees or persons external to the University and where deception is used at the time, immediately before or immediately following the activity. This also includes the deliberate falsification, concealment, destruction or use of falsified documentation used or intended for use for a normal business purpose or the improper use of information or position for personal financial benefit.

The concept of fraud involves fraudulent or corrupt conduct by internal parties or external entities targeting the University, or fraudulent or corrupt conduct by the University itself targeting external entities.

What is corruption?

Corruption is dishonest activity in which a person abuses his/her position of trust in order to achieve some personal gain or advantage for themselves, or provide an advantage/disadvantage for another person or entity.
