My answer -

The scientist that performed the cathode ray experiment leading to the discovery of electrons is<span> the scientist Sir Joseph John Thompson or J.J. Thompson. It was theorized after the discovery that electrons are present in the atom. In this model, the atom is composed mainly of electrons. It was describe as plum pudding because the electrons are dispersed within the atom.

P.S

Happy to help you have an AWESOME!!! day ^-^

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>
