Answer:
When a system is at equilibrium, <u>the process is not spontaneous at either direction.</u>
Explanation:
The process is not spontaneous at either direction , when a system is at equilibrium ΔG = 0, because -
We know that a negative ΔG indicates a forward-moving phase that is random.
We already know that a positive ΔG implies a non-spontaneous phase going forward.
Thus , here ΔG = 0, so the process is not spontaneous in either direction.
Answer: 1. n
2. n
3.
4. l
Explanation:
Principle Quantum Numbers : It describes the size of the orbital and the energy level. It is represented by n. Where, n = 1,2,3,4....
Azimuthal Quantum Number : It describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1).For l = 0,1,2,3... the orbitals are s, p, d, f...
Magnetic Quantum Number : It describes the orientation of the orbitals. It is represented as . The value of this quantum number ranges from -l to +l.
Spin Quantum number : It describes the direction of electron spin. This is represented as s.
Wait… what do you need help with lol
Answer:
In order to cancel the electrons,. the oxidation half reaction must be multiplied by 4 and the reduction half reaction must be multiplied by 3.
Explanation:
Oxidation reaction is defined as the chemical reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.
Reduction reaction is defined as the chemical reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.
The half cell reactions for the above reaction follows:
Oxidation half reaction:
Reduction half reaction:
Thus, in order to cancel the electrons,. the oxidation half reaction must be multiplied by 4 and the reduction half reaction must be multiplied by 3.
Thus,
4*Oxidation half reaction:
3*Reduction half reaction:
