a. Anna's chemistry class is going to be experimenting with AGNO3 today, which can stain hands and clothes. Anna is concerned about her jewelry, so as she gets ready for

school,she removes her gold (Au) ring and replaces it with a cheaper nickel (Ni) ring. Is this a good idea? Explain your answer. (4 points) i. Use the activity series of metals to determine what would happen if AgNO3 spilled on Anna's nickel (Ni) ring. Explain your answer. (2 points) ii. Using the activity series of metals, explain what would happen if AgNO3 spilled on her gold (Au) ring. (2 points) b. AGNO3 is a useful chemical that has many applications and can undergo many reactions.For each example, identify the type of reaction taking place. (4 points) i. 2AGNO, + Cu → Cu(NO), + 2Ag (1 point) ii. AGNO3 → Ag + 02 + NO2 (2 points) iii. AGNO3 + NaBr → AgBr + NaN0; (2 points) iv. Ag* + I → Agl (2 points)
