Pressure and volume are inversely proportional.
When one increases the other decreases and vice versa.
If you think about it, what have you done by squeezing the balloon to a smaller volume? you have brought all the atoms closer, thus they are more likely to collide and have less space to move around.
What is pressure? well, pressure is just the force that atoms apply on the walls of the container(in this example , the container is the balloon)
So by decreasing the volume, you have increased the pressure.
By halving the volume, you double the pressure.
OPTION D
Answer:
Explanation:
Because of the acid-base reaction, as sodium bicarbonate is introduced to the separatory funnel, the additional or unreacted HBr reacts vigorously to yield CO2 gas, which exits the separatory funnel together with any dissolved compound(s) in the ether layer. This is due to a wrong and incorrect selection of the solvent mixture and the addition of sodium bicarbonate to an acidic solution.
Nothing to do with it until it has leaked out of the separatory funnel. Even then, the student may separate the components from the remaining reaction mixture by washing the ether coating layer several times with brine water, then running it into a dry sodium sulfate bed and evaporating solvent ether under decreased pressure.
