What is the pressure in kPa of 2 moles of chlorine gas at a temperature of 5 degrees C
and a volume of 8 dm3?
Answer:
[tex]P=5.8x10^2kPa[/tex]
Explanation:
Hello.
In this case, since chlorine gas is assumed to behave ideally, we can use the ideal gas equation in order to compute the required pressure:
[tex]PV=nRT[/tex]
In such a way, since the temperature must be in kelvins and the volume in liters for the universal gas constant:
[tex]T=5+273.15=278.15K\\\\V=8dm^3*\frac{1L}{1dm^3}=8L[/tex]
Thus, we first compute the pressure in atm:
[tex]P=\frac{nRT}{V}= \frac{2mol*0.082\frac{atm*L}{mol*K}*278.15K}{8L}\\\\P=5.7atm[/tex]
Thus, the pressure in kPa turns out:
[tex]P=5.7atm*\frac{101.325kPa}{1atm}\\\\P=5.8x10^2kPa[/tex]

Consider an isolated system (no heat, matter, work exchange with the environment) consisting of three internal compartments: A on the left, B in the center, and C on the right.Initially the central volume B is filled with an ideal gas at 298K andtheothertwo are empty. Consider the following two processes:a.The valve to the A side is opened, the gas expands freely into compartment A, and the system comesto equilibrium. Then, the valve to the C compartment is opened, and the system comes to equilibrium. b.Both valves are opened simultaneously, the gas expands freely into both compartments, and the system comes to its equilibrium. Which process produces more entropy
Answer:
Both processes produce equal entropy
Explanation:
Three compartments : A , B , C
A to the left, B in center, C on the right
compartment B is filled at 298 k while A and C is empty
The process that produces more entropy is: both processes and this is because the system is an isolated system with no heat matter and work exchange with the environment. and also entropy is independent of the path a process follows so either valve been open does not affect the entropy in the system because the change in the internal energy of an isolated system = 0

You are given a sample of a Group II metal chloride, but the identity of the metal is unknown. Knowing that all Group II metal chloride compounds have the general formula, MCI2 and that the percentage of chlorine in the compound is 34.1%, what is the identity of the unknown substance?
Answer:
The identity of unknown substance is Barium.
Explanation:
The given compound has a formula of MCl2. And the percentage of chlorine in this compound is said to be 34.1 %. But, we know that the mass of chlorine in this compound is, 35.5*2 = 71 g
Therefore, if we let x be the total mass of the compound, then:
34.1% of x = 71 g
(0.341)x = 71 g
x = 71 g/0.341
x = 208.2 g
Hence, the mass of other atom M, must be:
M = x - 71 g
M = 208.2 g - 71 g
M = 137.2 g
Now, we look into periodic table in group II. We find that the element is Barium with atomic mass of 137 g.
The identity of unknown substance is Barium.
Barium forms a metal chloride whose percentage of chlorine is 34.1 %. The unknown substance is barium chloride.
We have a Group II metal chloride with a general formula MCl₂. The molar mass of Cl⁻ is 35.45 g/mol. The mass of 2 moles of Cl⁻ is:
[tex]2 mol Cl^{-} \times \frac{35.45g Cl^{-} }{1mol Cl^{-} } = 70.90g Cl^{-}[/tex]
70.90 g represents 34.1% of 1 mole of MCl₂. The molar mass of MCl₂ is:
[tex]70.90gCl^{-} \times \frac{100gMgCl_2}{34.1gCl^{-} } = 208gMgCl_2[/tex]
208 g of MCl₂ contains 70.90 g of Cl⁻. The mass of M²⁺ in 1 mole of MCl₂ is:
[tex]mMCl_2 = mCl^{-} + mM^{2+} \\\\mM^{2+} = mMCl_2 - mCl^{-} = 208g-70.9 g = 137.1 g[/tex]
Barium has a molar mass of 137.3 g/mol, so M must be barium. The unknown substance is barium chloride.
Barium forms a metal chloride whose percentage of chlorine is 34.1 %. The unknown substance is barium chloride.

A chemist carefully measures the amount of heat needed to raise the temperature of a 341.0 mg
sample of a pure substance from 8.4 ℃
to 21.5 ℃. The experiment shows that 4.03 J of heat are needed.
- What can the chemist report for the specific heat capacity of the substance?
Answer:
The specific heat of substance is 0.90 j/g.°C.
Explanation:
Given data:
Mass of sample = 341.0 mg (341.0/1000 = 0.341 g)
Initial temperature = 8.4 °C
Final temperature = 21.5 °C
Heat needed = 4.03 J
Specific heat capacity of substance = ?
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = T2 - T1
ΔT = 21.5 °C - 8.4 °C
ΔT = 13.1 °C
4.03 J = 0.341 g × c ×13.1 °C
4.03 J = 4.4671 g.°C × c
c = 4.03 J /4.4671 g.°C
c= 0.90 j/g.°C
The specific heat of substance is 0.90 j/g.°C.
