What is the net redox reaction that occurs when Au comes into contact with acidic KMnO4? (Use the lowest possible coefficients.
Natalka [10]

Answer:

3MnO₄⁻ + 24H⁺ + 5Au → 5Au³⁺ + 3Mn²⁺ + 12H₂O.

Explanation:

  • KMnO₄ is strong oxidizing agent which is reduced and oxidizes Au according to the two-half reactions:

The oxidation reaction: Au → Au³⁺ + 3e.

The reduction reaction: MnO₄⁻ + 8H⁺ + 5e → Mn²⁺ + 4H₂O.

  • To obtain the net redox reaction, we multiply the oxidation reaction by 5 and the reduction reaction by 5 to equalize the no. of electrons in the two-half reactions.

<em>So, the net redox reaction will be:</em>

<em>3MnO₄⁻ + 24H⁺ + 5Au → 5Au³⁺ + 3Mn²⁺ + 12H₂O.</em>

How many grams of Cl are in .46 moles of Cl?
trapecia [35]
From the periodic table you know that Cl has a molar mass of 35.35 g/m.  So if you just set up the dimensional analysis as so: (.46 moles Cl)*(35.45 grams Cl/1 mole Cl) and multiply out you get 16 grams of Cl if you follow the sig figs and 16.307 if you don't.
