Answer:
#1
The temperature that this happens is called the freezing point and is the same temperature as the melting point. As more energy is put into the system, the water heats up, the molecules begin moving faster and faster until there is finally enough energy in the system to totally overcome the attractive forces.
Explanation:
#2
Heating a liquid increases the speed of the molecules. An increase in the speed of the molecules competes with the attraction between molecules and causes molecules to move a little further apart. ... A decrease in the speed of the molecules allows the attractions between molecules to bring them a little closer together.
Answer:
435.38 L
Explanation:
From the question,
Applying ideal gas equation,
PV = nRT................... Equation 1
Where P = Pressure, V = Volume, n = number of moles, R = molar gas constant, T = Temperature.
Since Temperature and Pressure were constant,
V ∝ n
V/n = V'/n'.................... Equation 2
Where V and V' = the initial and final Volume of Ar respectively, n and n' = the initial and final moles of Ar respectively
make V' the subject of the equation
V' = Vn'/n............... Equation 3
Given: V = 100 L, n = 3.25 mol, n' = 14.15
Substitute into equation 3
V' = (100×14.14)/3.25
V' = 435.38 L
Answer:
Baking soda mixed with Vinegar
Explanation:
This is a chemical reaction that I have seen in my daily life. Vinegar is acidic while baking soda is a base. The 2 mix together to form carbonic acid and sodium acetate from sodium and bicarbonate ions.
Answer:
ΔG° = - RTLnK is used to find the standard cell potential given the equilibrium constant
Explanation:
for an ideal disolution:
⇒ ΔG = RT∑ni LnXi
∴ ΔG = ( μi - μi*)ni
∴ μ : chemical potential
∴ μ*: chem. potential of the pure component at T and P.
⇒ ΔG = μi - μi* = RT LnXi
for a equilibrium reaction:
⇒ ∑ νi*μi = 0
⇒ ΔGr = ΔG°+ RT Ln Kx = 0
⇒ ΔG° = - RT LnKx
Answer:
The reactions free energy 
Explanation:
From the question we are told that
The pressure of (NO) is 
The pressure of (Cl) gas is 
The pressure of nitrosly chloride (NOCl) is 
The reaction is
⇆ 
From the reaction we can mathematically evaluate the 
(Standard state free energy ) as
The Standard state free energy for NO is constant with a value
The Standard state free energy for 
is constant with a value
The Standard state free energy for 
is constant with a value
Now substituting this into the equation
The pressure constant is evaluated as
Substituting values
The free energy for this reaction is evaluated as
Where R is gas constant with a value of 
T is temperature in K with a given value of 
Substituting value
![\Delta G = -43 *10^{3} + 8.314 *298 * ln [0.0765]](https://tex.z-dn.net/?f=%5CDelta%20%20G%20%20%3D%20-43%20%2A10%5E%7B3%7D%20%2B%208.314%20%2A298%20%2A%20ln%20%5B0.0765%5D)
