A sample of CO2 is collected over water at 23oC. If the total pressure of the sample is 734 torr, and the vapor pressure of wate
2 answers:
<u>Answer:</u> The partial pressure of carbon dioxide is 712.8
<u>Explanation:</u>
Dalton's law of partial pressure states that the total pressure of the system is equal to the sum of partial pressure of each component present in it.
To calculate the partial pressure of carbon dioxide gas, we use the law given by Dalton, which is:
We are given:
Total pressure, = 734 torr
Vapor pressure of water, = 21.2 torr
Putting values in above equation, we get:
Hence, the partial pressure of carbon dioxide is 712.8

Answer:
(a) Constitutional Isomers
(b) Constitutional Isomers
Explanation:
Constitutional isomers are also known with the name Structural Isomers. These are the compounds which have same chemical formula but differ in arrangement of atoms i.e. structure.
Both the compounds <em>cis-1,3-dibromocyclohexane</em> and <em>trans-1,4-dibromocyclohexane</em> have the same chemical formula but have different structure as shown in the image below.
In the second case the compounds <em>2,3-dimethylhexane</em> and <em>2,3,3-trimethylpentane</em>, both have same chemical formula but have different structures which is shown in the image below.
Thus it is clear that in both the groups (a) and (b) the given compounds are Constitutional Isomers.
Answer:
124.91mL
Explanation:
Given parameters:
P₁ = 1.08atm
V₁ = 250mL
T₁ = 24°C
P₂ = 2.25atm
T₂ = 37.2°C
V₂ = ?
Solution:
To solve this problem, we are going to apply the combined gas law;
P, V and T represents pressure, volume and temperature
1 and 2 delineates initial and final states
Convert the temperature to kelvin;
T₁ = 24°C, T₁ = 24 + 273 = 297K
T₂ = 37.2°C , T₂ = 37.2 + 273 = 310.2K
Input the variables and solve for V₂
V₂ = 124.91mL
