Answer:
0.32 M
Explanation:
Step 1: Write the balanced reaction at equilibrium
Ag₂S(s) ⇌ 2 Ag⁺(aq) + S²⁻(aq)
Step 2: Calculate the concentration of Ag⁺ at equilibrium
We will use the formula for the concentration equilibrium constant (Keq), which is equal to the product of the concentrations of the products raised to their stoichiometric coefficients divided by the product of the concentrations of the reactants raised to their stoichiometric coefficients. It only includes gases and aqueous species.
Keq = [Ag⁺]² × [S²⁻]
[Ag⁺] = √{Keq / [S²⁻]}
[Ag⁺] = √{2.4 × 10⁻⁴ / 0.0023} = 0.32 M
Answer:
percentage error = 888.45 %
Explanation:
We calculate the percentage error using the following formula:
percentage error = [(estimated number - actual number) / actual number) × 100
percentage error = [(1001.3 - 101.3) / 101.3] × 100
percentage error = 888.45 %
Balance the equation first:
1C4H10 + 13O2 ----> 8CO2 + 10H2O
As we know oxygen is in excess, butane is the limiting reactant.
the ratio between butane and CO2 is 1-8
Therfore
1:8
6:x
x=48
48 moles of CO2 will be produced
