The stopper around the funnel reduced the amount of water that entered the bottle and so in the ten minutes the amount of water that entered the bottle did not reach the cotton wool to soak it.
Answer:
If pressure increases, then volume decreases and vice versa, when temperature is held constant.” When pressure increases, the same number of molecules, or matter, are being forced closer together to occupy a shrinking space, their volume decreasing while their density correspondingly increases.
Explanation:
I've put in some of the answers.
hope this helps :)
The answer is six because it is in group six A on the periodic table.
According to Arrhenius concept a base is one which can donate hydroxide ion in its aqueous solution.
Here NaOH is a base as it can donate OH-.
As NaOH is a strong base it will have very high dissociation constant.
Due to high dissociation constant if will almost completely dissociate into sodium ions and hydroxide ions.
Thus in a solution of NaOH we will expect the following two ions
Na^{+} + OH^{-}[/tex]
