Answer:
C. spontaneous at all temperatures
Explanation:
The spontaneity of reaction is determined by the sign of the gibbs free energy.
A negative sign denotes that the reaction is spontaneous, positive sign means the reaction is not spontaneous.
From the question;
ΔS° = +253 J/K
ΔH° = -125 kJ/mol
ΔG = ΔH° - TΔS°
From the data given, the condition in which we can obtain a negative value of G, is at any value of T.
For any value of T, G would always be a negative value.
This means the correct option is option C.
Answer:
weak acid
Explanation:
pH scale is from 0 to 14
pH =7 is for water which is neutral. it is neither acidic or basic as the hydrogen ion concentration is equal to hydroxyl ion concentration.
Lesser the pH value than 7 greater the acidic nature. And greater the pH value than 7 more the basic nature.
Given pH=3-7 So the indicated interval represents weakly acidic.
Answer:
2.68 cm^3
Explanation:
Density= Mass/Volume
so...
8.96 g/cm^3 = 24.01 g/ V
and then u solve so it would be 2.68 cm ^3
