London force:
London force is an intermolecular force which occurs between an atoms or molecules which are polar or non-polar and another atom or molecule which are polar or non-polar. Hence it occurs between all molecules or atoms. The London dispersion force is a temporary attractive force which cause due to temporary dipoles of electrons in two adjacent atoms. This is also known as induced dipole-induced dipole attraction. It is a weakest Intermolecular force.
therefore the correct answer is D.
attractive inter molecular forces
Answer:
Too much phosphorus in the water causes algae to grow faster than ecosystems can handle. Large growths of algae are called algal blooms and they can <u>severely reduce or eliminate oxygen in the water</u>, leading to illnesses in fish and the death of large numbers of fish.
Explanation
Futhermore, with a loss of fish the whole ecosystem will be upset and will be in need of serious recovery.
Answer The value of 
and 
is, 40.79 kJ and 37.7 kJ respectively.
Explanation :
Heat released at constant pressure is known as enthalpy.
The formula used for change in enthalpy of the gas is:
Now we have to calculate the work done.
Formula used :
where,
w = work done = ?
P = external pressure of the gas = 1 atm
= initial volume = 
= final volume = 
Now put all the given values in the above formula, we get:
Now we have to calculate the change in internal energy.
Thus, the value of and is, 40.79 kJ and 37.7 kJ respectively.
