When iron metal reacts with sulfuric acid, it produces iron (III) sulfate and hydrogen gas. Balance the equation: Fe + H2SO4 → F
gavmur [86]
<h3>Answer:</h3>
  1. Balanced Equation; 2Fe + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂
  2. Why balance?: To obey the law of conservation of mass
  3. Subscripts can not be changed, since they show the actual number of atoms of each element in a compound.
<h3>Explanation:</h3>
  • The balanced equation for the reaction between the iron metal and sulfuric acid to produces iron (III) sulfate and hydrogen gas is given by;

2Fe + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂

  • Balancing chemical equations ensures that they obey the law of conservation of mass which requires the mass of reactants and the mass of products to be equal.
  • Balancing is done by putting coefficients on reactants and products while not affecting the subscripts as subscripts show the actual number of atoms of an element in a compound.

When considering the relationship among standard free energy change, equilibrium constants, and standard cell potential, the equ
DedPeter [7]

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
