4 electrons are shared in an O2 molecule.
It shouldn't have any lone pairs since it is a tetrahedral structure. Ge has 4 valence electrons. Each H has 1 valence electron. Therefore, each H valence electron will pair with each valence electron on Ge.
Answer : The temperature in kelvins is, 
Explanation : Given,
= 178.5 KJ/mole = 178500 J/mole
= 161.0 J/mole.K
Gibbs–Helmholtz equation is :
As per question the reaction is spontaneous that means the value of 
is negative or we can say that the value of is less than zero.
The above expression will be:
Now put all the given values in this expression, we get :
Therefore, the temperature in kelvins is,
Hey there!
Sulphur is the element which has 6 electrons in the outermost shell.
WhereasCalcium,Neon have 2 and chlorine has 7.
Hope this explanation helps you :)
Have a good day :)
