It is a very large seamount and island created by hot-spot volcanism
Answer:
b. ΔS° > 0, ΔH° < 0
Explanation:
According the equation of Gibb's free energy -
∆°G = ∆°H -T∆°S
∆°G = is the change in gibb's free energy
∆°H = is the change in enthalpy
T = temperature
∆°S = is the change in entropy .
And , the sign of the Δ°G , determines whether the reaction is Spontaneous or non - Spontaneous or at equilibrium ,
i.e. ,
if
- Δ°G < 0 , the reaction is Spontaneous
- Δ°G > 0 , the reaction is non - Spontaneous
- Δ°G = 0 , the reaction is at equilibrium
The reaction has the value for ∆°H < 0 i.e. negative, and ∆°S > 0 i.e. , positive
Now ,
∆°G = ∆°H -T∆°S
= ( - ∆°H ) - T( + ∆°S )
= ( - ∆°H ) - T( ∆°S )
∆°G = negative
Hence ,
Δ°G < 0 , the reaction is Spontaneous .

Answer:
![[H_{3}O^{+} ] = 10^{-2}](https://tex.z-dn.net/?f=%5BH_%7B3%7DO%5E%7B%2B%7D%20%5D%20%3D%2010%5E%7B-2%7D)
mol/ L
Explanation:
Measure of [H₃O⁺] , i.e hydrogen ion concentration, indicates the acidity of the solution. The greater the concentration, the greater is the acidity. [H₃O⁺], this quantity can range from 10⁻¹ to 10⁻¹⁴ at ambient temperature(298K). This range is always temperature dependent.
Measure of acidity of a solution is expressed more conveniently using the notation of pH.
![pH = - log_{10}[H_{3}O^{+} ]](https://tex.z-dn.net/?f=pH%20%3D%20-%20log_%7B10%7D%5BH_%7B3%7DO%5E%7B%2B%7D%20%5D)
Using the above formula
![[H_{3}O^{+} ] = 10^{-(pH)}](https://tex.z-dn.net/?f=%5BH_%7B3%7DO%5E%7B%2B%7D%20%5D%20%3D%2010%5E%7B-%28pH%29%7D)
