Answer:
According to Charles law
Explanation:
volume is directly proportional to absolute temperature
Answer:
The answer is
<h2>1.20 L</h2>
Explanation:
Since the concentration , mass and molar mass of NaOH has been given we use the formula
<h3>
</h3>
To find the volume
where
C is the concentration
m is the mass
M is the molar mass
v is the volume
Making volume the subject we have
<h3>
</h3>
From the question
C = 1.25 M
m = 60 g
M = 40.0 g/mol
Substitute the values into the above formula and solve for the volume
We have
<h3>
</h3>
We have the final answer as
<h3>Volume = 1.20 L</h3>

Answer:
d. delta H is positive, and delta S is positive
Explanation:
The process of dissolution of NH4Cl is:
NH4Cl(s) → NH4+(aq) + Cl-(aq)
As the solution is cooled, the process is absorbing energy, that means ΔH > 0. (ΔH < 0 when the heat is released).
As there are produced 2 ions from 1 solid molecule, the disorder is increasing and ΔS > 0
The right answer is:
<h3>d. delta H is positive, and delta S is positive</h3>

Answer:
47.5 mL
Solving:
M1 = 4.00 M
V1 = ?
M2 = 0.760 M
V2 = 0.250 L
---
M1 * V1 = M2 * V2
V1 = ( M2 * V2 ) / M1
V1 = ( 0.760 * 0.250 ) / 4.00
V1 = ( 0.190 ) / 4.00
V1 = 0.0475 L
