What are requirements before you can compare the energy (or enthalpy or Gibbs free energy) for 2 compounds
Answers
The main two requirements to compare the energy for 2 compounds are the balanced chemical formula and the temperature of the compounds.
How do we calculate the free energy change?Gibb's free energy change of any reaction will be calculated by using the below equation as:
ΔG = ΔH - TΔS, where
ΔH = change in enthalpy
T = temperature
ΔS = change in entropy
Before calculating the free energy of any reaction you should first balance the given chemical reaction to check the involved moles of substance and also the value of temperature before & after the completion of reaction to check the nature of the reaction.
Hence balancing the equation and checking the temperature are the two requirements.

Carbonic acid, H₂CO₃ is a diprotic acid with Ka1 = 4. 3 × 10⁻⁷ and Ka2 = 5. 6 × 10⁻¹¹. What is the pH of a 0. 47 M solution of carbonic acid?
Answers
Based on the calculations, the pH of a 0.47 M solution of carbonic acid (H₂CO₃) is equal to 3.35.
How to calculate the pH of a solution?First of all, we would write a properly balanced chemical equation for these chemical reactions:
H₂CO₃(aq) ⇄ HCO₃⁻(aq) + H⁺(aq); Ka₁ = 4.3 × 10⁻⁷.
For the second chemical reaction:
HCO₃⁻(aq) ⇄ CO₃²⁻(aq) + H⁺(aq); Ka₂ = 5.6 × 10⁻¹¹.
Next, we set up an equation from the ICE table;
[HCO₃⁻] = [H⁺] = x.
[H₂CO₃] = 0.47 - x.
Ka₁ = ([HCO₃⁻] × [H⁺])/[H₂CO₃].
4.3 × 10⁻⁷ = (x × x)/(0.47 - x).
4.3 × 10⁻⁷ = x²/(0.47 - x).
x² = 0.0000002021 - 4.3 × 10⁻⁷x
x² + 4.3 × 10⁻⁷x - 0.0000002021 = 0
By solving the quadratic equation, we have:
x = [H⁺] =0.000449 M.
Now, we can determine the pH by using this formula;
pH = -log[H⁺]
pH = -log(0.000449 M).
pH = -(-3.35)
pH = 3.35.
Note: The second dissociation from Ka₂ would be so small, so it's considered negligible.

mL and contains 441 g of HCI?
Answers
Taking into account the definition of molarity, the molarity of the solution is 8.066 [tex]\frac{moles}{liter}[/tex].
Definition of molarityMolar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.
The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:
[tex]Molarity=\frac{number of moles}{volume}[/tex]
Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].
Molarity of a hydrochloric acid solutionIn this case, you know:
number of moles= 441 g× [tex]\frac{1mole}{36.45 g}[/tex]= 12.099 moles (being 36.46 [tex]\frac{g}{mole}[/tex] the molar mass of NaNO₃, this is,the amount of mass that a substance contains in one mole.)volume= 1500 mL= 1.5 L (being 1000 mL= 1 L)Replacing in the definition of molarity:
[tex]Molarity=\frac{12.099 moles}{1.5 L}[/tex]
Solving:
molarity= 8.066[tex]\frac{moles}{liter}[/tex]
Finally, the molarity of the solution is 8.066 [tex]\frac{moles}{liter}[/tex].

A sample of helium had a volume of 3.20x102 mL at STP. What will be it’s new volume of the temperature is increased to 425.0k and it pressure is increased to 3.50 atm?
Answers
The new volume of the sample of helium gas as its temperature and pressure increases to the given values is 1.40×10²mL.
Combined gas law
Combined gas law put together both Boyle's Law, Charles's Law, and Gay-Lussac's Law. It states that "the ratio of the product of volume and pressure and the absolute temperature of a gas is equal to a constant.
It is expressed as;
P₁V₁/T₁ = P₂V₂/T₂
Given the data in the question;
Initial volume of helium gas V₁ = 3.20 × 10²mL = 0.32LAt standard remperature and pressure
Initial pressure P₁ = 1.0atmInitial temperature T₁ = 273.15KFinal pressure P₂ = 3.50atmFinal temperature T₂ = 425.0KFinal volume V₂ = ?To calculate the new volume of the helium gas, we subtsitute our given values into the expression above.
P₁V₁/T₁ = P₂V₂/T₂
P₁V₁T₂ = P₂V₂T₁
V₂ = P₁V₁T₂ / P₂T₁
V₂ = ( 1.0atm × 0.32L × 425.0K ) / ( 3.50atm × 273.15K )
V₂ = 136LatmK / 956.025atmK
V₂ = 0.14L
V₂ = 1.40×10²mL
Therefore, the new volume of the sample of helium gas as its temperature and pressure increases to the given values is 1.40×10²mL.
