Answer : The final volume of balloon will be, 3.35 L
Explanation :
Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.
or,
where,
= initial pressure = 789 mmHg
= final pressure = 632 mmHg
= initial volume = 2.68 L
= final volume = ?
Now put all the given values in the above equation, we get:
Therefore, the final volume of balloon will be, 3.35 L
Answer:
Option B
Explanation:
The name of the molecule is;
1,1,1,3,3,3-Hexachloropropanone
Now, we can see that it contains propanone which is also called acetone. So it will have a double bond with Carbon(C) and Oxygen (O).
Option B has that double bond between C and O that indicates it propanone or acetone.
Thus, it is the correct option.
