Redox is a type of chemical reaction in which the oxidation states of the substrate change. Electrons will move from the right electrode to the left. Describe the role/what happens to copper and silver in the redox process. Copper is in the left beaker and silver is in the right. use CER, claim, evidence, and, reasoning. Claim is your answer, evidence is from the image and, reasoning is your explanation.

3Zn + 2NO,+ 8H*→2NO + 3Zn2++ 4H,0 In the above reaction, the oxidation state of nitrogen changes from | to How many electrons are transferred in the reaction?

You are tasked with creating a pourboix diagram of sulfur speciation. The relevent species are SO42-, HSO42-, S, H2S, and HS-. The total copper is 10^-6 mol. Set and balence the redox reactions needed for this question and explain how you landed on those reactions.

Silver tarnish is the result of the oxide on the silver surface reacting with hydrogen sulfide (H2S) in air. This leaves a black film of silver sulfide (Ag2S).Polishing the tarnished silver will restore the shine but at the expense of some of the silver metal. An alternative process is to allow aluminumto reduce the silver in the presence of a solution of sodium bicarbonate (baking sodium) electrolyte. 1. Assume that Aluminumand Silver Sulfideare the starting substances (reactants) in the reaction: a.Write a balanced chemical equation describing the ”re-creation” of silver, using the information in the case study.    b.State the names of the products that are produced from this reaction.   c.What type of reaction(s) is/are being represented by the chemical reaction you wrote in part (a)?   d.Is the reaction in part (a) an oxidation-reduction (redox) reaction?     e.If this is a redox reaction, then identify the following:   What is undergoing oxidation (what is being oxidized)?…
