question 134

Multiple Choice

What is the reduction half-reaction for the reaction between iron(II) sulfate and potassium permanganate in a sulfuric acid solution?
5Fe²⁺(aq) + MnO₄^-(aq) + 8H⁺(aq) → 5Fe³⁺(aq) + Mn²⁺(aq) + 4H₂O(l)

• A)MnO₄^-(aq)+ 3e^- → Mn²⁺(aq)+ 4H₂O(l)
• B)MnO₄^-(aq)+ 8H⁺(aq)+ 5e^- → Mn²⁺(aq)+ 4H₂O(l)
• C)5Fe²⁺(aq)→ 5Fe³⁺(aq)+ 5e^-
• D)Fe²⁺(aq)+ 2e^- → Fe(s)
• E)MnO₄^-(aq)+ 5e^- → Mn²⁺(aq)+ SO₄^2-(aq)

Definitions:

Significance Level

A threshold used in statistical hypothesis testing to determine whether a result is statistically significant, typically denoted by alpha (α), and representing the probability of rejecting the null hypothesis when it is in fact true.

Variances

A measure of the dispersion representing the average of the squared differences from the Mean, showing how far each value in the set is from the mean.

Small Grocery Stores

Retail establishments primarily engaged in offering a range of food items and basic household goods, usually smaller in size and scope compared to supermarket chains.

Significance Level

The threshold below which a p-value is considered statistically significant, indicating the probability of rejecting the null hypothesis when it is true.
