The half-reaction are:
Cd ---> Cd(OH)₂
The oxidation number of Cd changed from 0 to +2. So, the number of mol electron transferred here is 2.
NiO(OH) --> Ni(OH)₂
The oxidation number of Cd changed from +3 to +2. So, the number of mol electron transferred here is 1.
Now, the greatest common factor would be 2. So, we use n=2 for the formula for ΔG°. F is Faraday's constant equal to 96,485 J/mol e.
ΔG° = nFE° = (2)(96,485)(1.5) =<em> 289,455 J</em>
When light hits a surface, some of it is absorbed and some of it is reflected. The light that is reflected is the color of the object in that light. For example, a blue object absorbs all the colors of the spectrum except blue, it reflects blue light. hope this can help.
Explanation:
Uranium have an unstable nuclei , hence it is a radioactive element , and radioactive element can undergo radioactive decay like the alpha decay , beta decay .
Radioactive decay is a spontaneous breakdown of the atomic nucleus which , results in the release of energy along with radioactive particles , like alpha , beta , gamma etc .
Hence ,
The mass is lost from a sample of uranium .
<span>Let's </span>assume that the gas is an ideal gas. Then we can use ideal gas equation,<span>
PV = nRT<span>
</span>Where,
P = Pressure of the gas (Pa)
V = volume of the gas (m³)
n = number of moles (mol)
R = Universal gas constant (8.314 J mol</span>⁻¹ K⁻¹)<span>
T = temperature in Kelvin (K)
<span>
The given data for the </span></span>gas is,<span>
P = ?
V = 9.5 L = 9.5 x 10</span>⁻³ m³<span>
T = (273 + 20) K = 293 K
R = 8.314 J mol</span>⁻¹ K⁻¹<span>
n = 1.2 mol
by applying the formula,
P x </span>9.5 x 10⁻³ m³ = 1.2 mol x 8.314 J mol⁻¹ K⁻¹ x 293 K
<span> P = 307705.5 Pa
P =3.08 x 10</span>⁵ Pa
<span>
Hence, the pressure of the gas is </span>3.08 x 10⁵ Pa.<span>

Rubisco is a super important enzyme in plants that first captures CO2 to begin the process of the Calvin cycle. It's the most important enzyme by far because it starts the entire process of Carbon Fixation.
