10 miles per hour because 500 divided by 50 is 10
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.
Answer:
No moon has no light.
Explanation:
It only reflects the light coming from the sun. Only star produces light and moon is a satellite that revolvs around the earth.
<span>The liquid form of matter is usually more dense than its gas form. This is because liquid molecules are closer together compared to gas molecules. An exception, however, is water. Water's solid form or ice is less dense than its liquid form because of the orientation of hydrogen bonds that lowers its density.</span>
