In order to compute this, we must first take a couple of assumptions of:
1) The laboratory size so we can calculate its volume
2) The number of students working in the lab so we know the total gas produced
Let the lab be
11 m × 9 m × 6 m
The volume then computes to be:
594 m³
We know that
1 Liter is 1 dm³
1 m = 10 dm
1 m³ = 1000 dm³
Therefore, the room volume in liters is:
594,000 Liters
Let there be 30 students in the laboratory
Total gas being produced:
6 × 30
= 180 Liters
This works out to be:
0.03% of Hydrogen by volume
Therefore, there is no risk of explosion given our assumption of size and students.
Magnesium silicate I hope this help
The correct answer is: by the transfer of one or more electrons from one atom to another.
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:
![pOH = pKb + log(\frac{[NH_{4}Cl]}{[NH_{3}]})](https://tex.z-dn.net/?f=%20pOH%20%3D%20pKb%20%2B%20log%28%5Cfrac%7B%5BNH_%7B4%7DCl%5D%7D%7B%5BNH_%7B3%7D%5D%7D%29%20)
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.
I hope it helps you!
Evaporating? But that’s with a boiling liquid
