Answer:
Explanation:
At low temperatures or high pressures, real gases deviate significantly from ideal gas behavior. The kinetic theory assumes that gas particles occupy a negligible fraction of the total volume of the gas. It also assumes that the force of attraction between gas molecules is zero.
I hope I helped you! :)
Answer:
Explanation:
Firstly, write the expression for the equilibrium constant of this reaction:
Secondly, we may relate the change in Gibbs free energy to the equilibrium constant using the equation below:
From here, rearrange the equation to solve for K:
Now we know from the initial equation that:
Let's express the ratio of ADP to ATP:
Substitute the expression for K:
Now we may use the values given to solve:
Answer:
34.2 g
Explanation:
In the Hall-Heroult process, Al³⁺ (from Al₂O₃) is reduced to Al. The reduction half-reaction is:
Al³⁺ + 3 e⁻ ⇒ Al
We can establish the following relations:
- 1 A = 1 c/s
- 1 mole of e⁻ has a charge of 96468 c (Faraday's constant)
- 1 mol of Al is produced when 3 moles of e⁻ circulate
- The molar mass of Al is 26.98 g/mol.
Suppose a current of 6800 A is passed through a Hall-Heroult cell for 54.0 seconds. The mass of Al produced is:
Explanation:
Given that,
The frequency of electromagnetic spectrum is
(A) Let the wavelength of this radiation is . We know that,
So, the wavelength of this radiation is .
(B) Let E is the energy associated with this radiation. Energy of an electromagnetic radiation is given by :
h is Planck's constant
1 kcal = 4184 J
It means,
Hence, this is the required solution.
Taking the compound with the metallic counterpart of highest mass would be the answer. Looking at the periodic table, it is easy to realize that K has the highest mass out of H, Li, K, and Cl. Therefore, the answer is (2) KCl.
