Answer:

The prefix "Tetra" implies 4 Bromine atoms. The prefix "Deca" implies 10 fluorine atoms.
Answer:

Explanation:
Hello,
In this case, the reaction is:

Thus, the law of mass action turns out:
![Kc=\frac{[CH_3CH_2OH]_{eq}}{[H_2O]_{eq}[CH_2CH_2]_{eq}}](https://tex.z-dn.net/?f=Kc%3D%5Cfrac%7B%5BCH_3CH_2OH%5D_%7Beq%7D%7D%7B%5BH_2O%5D_%7Beq%7D%5BCH_2CH_2%5D_%7Beq%7D%7D)
Thus, since at the beginning there are 29 moles of ethylene and once the equilibrium is reached, there are 16 moles of ethylene, the change
result:
![[CH_2CH_2]_{eq}=29mol-x=16mol\\x=29-16=13mol](https://tex.z-dn.net/?f=%5BCH_2CH_2%5D_%7Beq%7D%3D29mol-x%3D16mol%5C%5Cx%3D29-16%3D13mol)
In such a way, the equilibrium constant is then:

Thereby, the initial moles for the second equilibrium are modified as shown on the denominator in the modified law of mass action by considering the added 15 moles of ethylene:

Thus, the second change,
finally result (solving by solver or quadratic equation):

Finally, such second change equals the moles of ethanol after equilibrium based on the stoichiometry:

Best regards.
Answer:
Equilibrium will lie to the right.
Explanation:

That means HF is stronger acid than
.
Alternatively, it can be said that
is a stronger base than
.
Therefore HF readily gives proton to
to form
and
than the reverse reaction.
So, the equilibrium will lie more towards the right i.e. towards formation of
and
.
