Answer:
None of these
Explanation:
For a reaction;
aA + bB ------>cC + dD
The equilibrium constant K is given as;
K = [C]^c [D]^d/[A]^a [B]^b
The equilibrium constant neither depends on the concentrations of the reactants nor on that of the products.
Let us recall that at equilibrium, the concentrations of reactants and products remain largely constant. This implies that, concentration of species do not appreciably change at equilibrium because the rates of forward and reverse reactions are equal.
Hence, the equilibrium constant neither depends on the initial/final concentrations of the reactants nor on the initial/final concentrations of the products.
When fireworks go off, they produce smoke, which is evidence of a new substance being created.
Answer:
16.9 mol
Explanation:
8Al + 3Fe₃O₄ ⟶ 4Al₂O₃ + 9Fe
You want to convert moles of Fe₃O₄ to moles of Al.
The molar ratio is 8 mol Al:3 mol Fe₃O₄. Calculate the moles of Al
Moles of Al = 6.34 × 8/3
Moles of Al = 6.34 × 2.667
Moles of Al = 16.9 mol Al
