Question

Circle the questions that have been assigned. Sodium metal is also readily oxidized by oxygen. If the product of the reaction were dissolved in water, what would be the color of the litmus for a litmus test? Explain. What is the product? Oxygen gas has an oxidizing strength comparable to that of nitric acid. Patina is a green or greenish-blue coating that forms on copper metal in the environment. Account for its formation. Test tube 7. Does the ferrous ion in the Fe(NH_4)_2(SO_4)_2 solutions function as an oxidizing agent or a reducing agent? Explain. Test tube 8. a. What was the color change of the Tin the reaction? b. Does the T solution function as an oxidizing agent or a reducing agent? Explain. Eliseo couldn't find the 6 M HCI and so used 6 M HNO_3 for testing the metals instead. His logic? Both are strong acids. Explain how the results of the experiment would have been different. Single displacement, double displacement, and decomposition reactions may all be redox reactions. Identify the type of redox reactions in Part C. Explain. a. on the basis of your intuitive understanding of the chemical properties of sodium and gold, and gold, where in your activity series would you place sodium and gold? b. Will hydrochloric acid react with gold metal to produce gold(III) ions and hydrogen gas? Explain.

Part A.2. Oxygen gas has an oxidizing strength comparable to that of nitric acid. Patina isa green or greenish-blue coating that forms on copper metal in the environment. Accountfor its formation.

-The green coating is mainly Copper (II) Carbonate CuCO3 .

it caused by slowchemical reactions involving the copper metal and water and carbon dioxide

Eliseo couldn't find the 6 M HCl and so used 6 M HNO3 for testing the metals instead. His logic? Both are strong acids. Explain how the results pf the experiment would have been different.

If Eliseo had used the 6 M HNO3 as a substitution for 6 M HCl, the product would have yielded a blue solution, whereas there would actually be no reaction had he used the 6 M HCl as instructed.

Single displacement, double displacement, and decomposition reactions may all be redox reactions. Identify the type of redox reaction in Part C.

In Part C, the redox reactions were single displacement reactions.

as the metal cations dissociate to leave the oxidizing agent on its own and then the metal being tested combines with the metal in the cation.
