6832 J of heat energy is applied to 5.9 mol of water. If the original temperature of the water was 18.60C, the final temperature
1 answer:
Answer: The final temperature of the water will be
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
Q = Heat absorbed= Joules
m= mass of water =
c = specific heat capacity =
Initial temperature of the water = =
Final temperature of the water = = ?
Putting in the values, we get:
The final temperature of the water will be

Answer:
The pH of the resulting solution is 9.02.
Explanation:
The initial pH of the buffer solution can be found using the Henderson-Hasselbalch equation:
Now, the perchloric acid added will react with ammonia:
Also, the moles of ammonium chloride will increase in the same quantity according to the following reaction:
NH₃ + H₃O⁺ ⇄ NH₄⁺ + H₂O
Finally, we can calculate the pH of the resulting solution:
Therefore, the pH of the resulting solution is 9.02.
