Answer:
2NaCl + H2SO4 ----> Na2SO4 + 2HCl
Explanation:
Bromine and Iodine are both
totally soluble in mineral oil because these substances are all made up of
non-polar molecules. And because water is a polar molecule, Bromine and Iodine
is not soluble in it.
Non polar solvents contain
bonds that have similar electronegativity, an example of this is carbon and
hydrogen such as gasoline. Some other examples are pentane, hexane, benzene
and toluene.

Answer:
Buffer 1.
Explanation:
Ammonia is a weak base. It acts like a Bronsted-Lowry Base when it reacts with hydrogen ions.
.
gains one hydrogen ion to produce the ammonium ion
. In other words,
is the conjugate acid of the weak base
.
Both buffer 1 and 2 include
- the weak base ammonia
, and - the conjugate acid of the weak base
.
The ammonia
in the solution will react with hydrogen ions as they are added to the solution:
.
There are more
in the buffer 1 than in buffer 2. It will take more strong acid to react with the majority of
in the solution. Conversely, the pH of buffer 1 will be more steady than that in buffer 2 when the same amount of acid has been added.
