Answer:
Attraction between molecules of methane in liquid state is primarily due to "London dispersion force".
Explanation:
Methane is a non-polar and aprotic molecule. Hence there is no dipole moment in methane as well as no chance of hydrogen bonding formation by methane.
We know that all molecules contain electrons. Therefore transient dipole arises in every molecule due to revolution of electrons around nucleus in a non-circular orbit. Hence an weak intermolecular attraction force is always present in every molecule as a result of this which is termed as "London dispersion force".
So, attraction between molecules of methane in liquid state is primarily due to "London dispersion force".
Answer:
2.5 Hz
Explanation:
Formula for the given question is:
Velocity= frequency X Wavelength.
v= f X λ.
25 = 10 X f
f= 2.5 Hz
The answer is 5 if u multiple
The enthalpy change for the reaction 2K + S + K2S using the following thermochemical reactions is mathematically given as
dn=70.7kg
<h3>What is the enthalpy change for the reaction?</h3>
Generally, the equation for the Chemical reaction is mathematically given as
2k+s----->K2S
Therefore
KS+K----->K2S
Therefore
dn=dn1+dn2
dn=32.5+38.2
dn=70.7kg
In conclusion, the enthalpy change is
dn=70.7kg
