It causes earthquakes say you had to glass plates you eat from and smash them together and they make a loud sound and brake into each other thats like the diverging plates
15 grams of NH3 can be dissolved
<h3>Further explanation</h3>
Given
50 grams of water at 50°C
Required
mass of NH3
Solution
Solubility is the maximum amount of a substance that can dissolve in some solvents. Factors that affect solubility
- 1. Temperature:
- 2. Surface area:
- 3. Solvent type:
- 4. Stirring process:
We can use solubility chart (attached) to determine the solubility of NH3 at 50°C
From the graph, we can see that the solubility of NH3 in 100 g of water at 50 C is 30 g
So that the solubility in 50 grams of water is:
= 50/100 x 30
= 15 grams
Ms ( mass of solute): 33,6g
mss (mass of solution): 33,6+192g = 225,6g
__________________
C = ms/mss × 100%
C = 33.6/225.6 × 100%
C = 14,89% ≈ 14,9%

Answer:
B. a chemical reactions that occurs in the chloroplast of a plant.
Explanation:
Answer:
b. 0.100M
Explanation:
The balanced chemical reaction is: NaOH + HA ⇒ H₂O + NaA
The NaOH and HA react in a 1:1 molar ratio, so at the equivalence point, the amount of NaOH added equals the amount of HA that was present in the solution.
The amount of NaOH that was added can be calculated and set equal to the amount of HA that must have been present to react with it.
n = CV = (0.200 mol/L)(12.5 mL) = 2.50 mmol NaOH = 2.50 mmol HA
Thus, there were 2.50 mmol of HA in 25.0 mL. The concentration can be calculated as follow:
C = n/V = (2.50 mmol)/(25.0mL) = 0.100 M
