Question

The diagram below represents a chemical cell at 298 K. When the switch is closed, electrons flow fromCaptionless Image(1) Al³⁺(aq) to Ni²⁺(aq)(2) Ni²⁺(aq) to Al³⁺(aq)(3) Al(s) to Ni(s)(4) Ni(s) to Al(s)

Answer 1

INFORMATION:

We know that:

- the diagram represents a chemical cell at 298 K

And we must determine how is the flow of electrons when the switch is closed

STEP BY STEP EXPLANATION:

To determine it, we need to know that the flow of electron will be from the particles undergo oxidation to particles undergo reduction.

Analyzing the equation, we can see that Al particles undergo oxidation and Ni particles undergo reduction

Then, electrons will flow from Al(s) to Ni(s)

ANSWER:

(3) Al(s) to Ni(s)
