CHEM 118 Activity Series and Redox Reactions Questions

Description

Hi

I have HW in chemistry class, they are 5 Qs and I need the full answers to give them to my teacher, Just watch the videos and answers the Qs

QUESTION 1

  1. Observations of metal and solution combinations

    Zinc Copper Lead Magnesium
    0.1 M Zn(NO3)2
    0.1 M Cu(NO3)2
    0.1 M Pb(NO3)2
    1 M HCl
    Hot water

QUESTION 2

  1. List the expected activity series from your textbook or other reference. Arrange the series with the most active metal (the strongest reducing agent) at the top. Be sure to include the reference (H2 (g) –> 2H+ (aq) + 2e) in the expected series. Be sure to the half oxidation reactions that you are using are balanced and the physical states are included.1) 2) 3) 4) 5)

QUESTION 3

  1. List the observed activity series that you obtained from this experiment.1) 2) 3) 4)

QUESTION 4

  1. Based on your activity series and your knowledge of periodic trends, what relationship exists between the ease of oxidation of metals and ionization energy? Explain. (In your explanation, give a definition of ionization energy)

QUESTION 5

An aqueous solution containing 2.54 g of aluminum nitrate is added to a 40.0 mL of 0.37 M solution of ammonium carbonate. How many grams of precipitates are expected to form?
