Hydrogen ions because acid dissociates into hydrogen ions when placed in aqueous solutions aka water
Answer:
ΔG = - 442.5 KJ/mol
Explanation:
Data Given
delta H = -472 kJ/mol
delta S = -108 J/mol K
So,
delta S = -0.108 J/mol K
delta Gº = ?
Solution:
The answer will be calculated by the following equation for the Gibbs free energy
G = H - TS
Where
G = Gibbs free energy
H = enthalpy of a system (heat
T = temperature
S = entropy
So the change in the Gibbs free energy at constant temperature can be written as
ΔG = ΔH - TΔS . . . . . . (1)
Where
ΔG = Change in Gibb’s free energy
ΔH = Change in enthalpy of a system
ΔS = Change in entropy
if system have standard temperature then
T = 273.15 K
Now,
put values in equation 1
ΔG = (-472 kJ/mol) - 273.15 K (-0.108 KJ/mol K)
ΔG = (-472 kJ/mol) - (-29.5 KJ/mol)
ΔG = -472 kJ/mol + 29.5 KJ/mol
ΔG = - 442.5 KJ/mol
83.3 mL
Explanation:
M
= 3M
V = 50mL
M
= 1.80M
Unknown:
V = ?
Solution:
To solve this problem we must understand that the initial and final number of moles remains the same.
Number of moles = molarity x volume
Molarity x volume of initial solution = Molarity x volume of final solution
Therefore:
M x V = M x V
M is the molarity
V is the volume
i = initial state
f = final state
input the parameters;
3 x 50 = 1.8 x V
V = 83.3 mL

Answer:
NOUN
a thing that is composed of two or more separate elements; a mixture
Explanation:
basically a mixture
Yes an objects mass does not change its mass is the density or physical makeup of an object mass is not the weight of an abject
