Explanation:
The given data is as follows.
T = 298 K, 
= -5645 kJ/mol
= -5798 kJ/mol
Relation between 
and 
are as follows.
= 
-5798 kJ/mol = -5645 kJ/mol - 
-153 kJ/mol = -
= 0.513 kJ/mol K
Now, temperature is 
= (37 + 273) K = 310 K
Since, =
= 
= (-5645 kJ/mol - 159.03 kJ/mol)
= -5804.03 kJ/mol
As, change in Gibb's free energy = maximum non-expansion work
= -5804.03 kJ/mol - (-5798 kJ/mol)
= -6.03 kJ/mol
Therefore, we can conclude that the additional non-expansion work is -6.03 kJ/mol.
Answer:
18.45L
Explanation:
V1 = 12.3L
T1 = 40K
T2 = 60K
V2 = ?
This question involves the use of Charles law which states that the volume of a fixed mass of gas is directly proportional to its temperature provided that pressure remains constant.
Mathematically,
V = kT k = V/T
V1 / T1 = V2 / T2 = V3 / T3 =.......=Vn / Tn
V1 / T1 = V2 / T2
V2 = (V1 × T2) / T1
V2 = (12.3 × 60) / 40
V2 = 18.45L
The final volume of the gas is 18.45L
21. change in temperature, change in color, or noticeable odor (after reaction has begun)
22. Picture... Wasn't so sure about this since no charge was given, so I suspected it has a charge of 2. If you have more information on this I would be glad to help, and I can't tell what is happening with the calculations given. It would be helpful if you can add spaces or put a line break.
23. An ion is an atom or molecule with an electric charge. It is formed when atoms lose or gain electrons. There are two types of ions: cations (net positive charge) and anion (net negative charge).
24. Picture
25. a) dinitrogen tetrahydride
b) phosphorus triiodide
c) lithium hydroxide
Answer:
The wavelength of wave is 0.33 ×10²⁰ m.
Explanation:
Given data:
Frequency of wave = 9.12×10⁻¹² Hz
Wavelength of wave = ?
Solution:
Formula:
Speed of light = wavelength × frequency
c = λ × f
λ = c/f
This formula shows that both are inversely related to each other.
The speed of light is 3×10⁸ m/s
Frequency is taken in Hz.
It is the number of oscillations, wave of light make in one second.
Wavelength is designated as "λ" and it is the measured in meter. It is the distance between the two crust of two trough.
Now we will put the values in formula.
λ = 3×10⁸ m/s / 9.12×10⁻¹² Hz
Hz = s⁻¹
λ = 0.33 ×10²⁰ m
The wavelength of radiation is 0.33 ×10²⁰ m .
Answer:
-375.9_KJ/(mol)
Explanation:
H(T2 ) ≈ H(T1)+CPΔT
Specific heat of Carbon is 0.71 J/g K.
At 283.15 the heat capacity is 37.12 J/(mol*K)
Kirchhoff's law
H(T2 ) ≈ H(T1)+CPΔT
Where
H(T1) and H(T2 ) are the heat of formation of CO2 at temperatures T1 and T2
CP is the heat capacity
Thus we have and ΔT is the temperature change
H(T2 ) ≈ -393.51×10^3+CP×(500-25)
= -393.51×10^3+37.12×(500-25)
= -375878 J/(mol)
= -375.9KJ/(mol)
