What is the standard cell notation of galvanic cell made with zinc (zn) and aluminum (al)?
Zn(s)/Zn2+(aq)//Au+(aq)/Au(s)
What is the voltage of a galvanic cell made with silver an nickel?
The voltage of a galvanic cell made with silver and nickel will depend on the specific conditions of the cell, such as the concentrations of the electrolytes and the temperature. Typically, a cell made with silver and nickel could have a voltage range between 0.8 to 1.0 V.
What is contained in the electrolyte solutions of a galvanic cell?
The electrolyte solutions in a galvanic cell contain ions that allow for the flow of electric current between the two half-cells. These ions help maintain charge balance and facilitate the chemical reactions that generate electricity.
What is the voltage of the galvanic cell made with silver and nickel?
The voltage of a galvanic cell made with silver and nickel will depend on the specific half-reactions involved. However, using standard reduction potentials, the cell voltage can be calculated as the difference between the reduction potentials of the two metals.

What is galvanic cell made of?
Two electrodes in electrolyte solutions
What are the half-reactions for the galvanic cell with Zn and mg electrodes?
Zn2+(aq) + 2e- = Zn(s) and Mg(s) = Mg2+(aq) + 2e-
What is source of electrical energy in galvanic cell?
The source of electrical energy in a galvanic cell is the chemical reaction that takes place between the two half-cells. This reaction creates a flow of electrons from the oxidation half-reaction to the reduction half-reaction, generating an electric current. The movement of electrons through an external circuit is what produces the electrical energy.
What is the standard cell notation for a galvanic for a galvanic cell with aluminum and gold electrodes?
The standard cell notation for a galvanic cell with aluminum and gold electrodes is represented as: Al(s) | Al³⁺(aq) || Au³⁺(aq) | Au(s). In this notation, the anode (aluminum) is listed on the left, and the cathode (gold) is on the right. The double vertical line (||) indicates the salt bridge or separation between the two half-cells. The state of each component (solid or aqueous) is also noted.
How is an electrolytic cell different from a galvanic cell?
Electrons flow in the opposite direction.
What is the voltage of a galvanic cell made with silver and nickel?
1.05 V
What are the half reactions for a galvanic cell with Zn and Mg electrodes apex?

How does a galvanic cell work?
.. A redox reaction at two electrodes causes electrons to flow.
Which is formed when a standard hydrogen half-cell is connected with a salt bridge to a standard zinc half-cell?
This forms a galvanic (voltaic) cell (battery).
