Answer:
D
Explanation:
It occurs when the outermost electrons are permanently transferred to another atom.
The amount of solvent increases, since the solvent is the one diluting the solution, the more you want your solution diluted, the more of solvent you'd use. :)
Answer is: B) The kinetic energy is increasing proportional to the mass of the bowling ball.
Kinetic energy has to do with the speed of an object and how much mass it has; basically how the object is moving.
Ek = 1/2 · m(bowling ball) · v²(bowling ball).
m is mass; v is speed of bowling ball.
The standard unit of kinetic energy is the joule.
Explanation:
In sugar solution 200 g has sugar 10 g
In sugar solution 100 g has sugar 10/200 × 100
= 5 %w/w
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 .
