Lab 9 Worksheet

This assignment requires the accompanying

Lab 9 Manual
(separate document on D2L).

1. Activity.

While performing the Activity (primarily
Steps 8,
10 and
11 on
page 9 of the
Lab 9 Manual), complete the
Data Table below. Be sure to record your observations – especially evidence of chemical activity such as color changes, bubbling, and the production of heat. If there is no obvious reaction, indicate that no evidence of a reaction was observed.

2. Data Interpretation.

a. Using the
number of reactions observed from the
Data Table above, list the metals (copper (Cu), iron (Fe), and magnesium (Mg)) in order from
most
to
least reactive.

b. For each metal/metal ion combination listed in the
Data Table that
gave evidence of a chemical reaction, perform the following steps:

· Write the
oxidation half-reaction.

· Write the
reduction half-reaction.

· Write the
balanced net ionic equation.

· Write the
overall single-displacement reaction.

· Identify the
reducing agent.

· Identify the
oxidizing agent.

Use the subsections below to help organize your presentation. There is space for four different chemical reactions – you may have less, meaning you may not use all four sections. The chemical reactions are generically labeled “First”, “Second”, etc. This is not to imply the chemical reactions must be stated in a particular order – any order should be fine, it’s just the responses for a given chemical reaction that are specific.

For the
First Chemical Reaction

· Write the
oxidation half-reaction.

· Write the
reduction half-reaction.

· Write the
balanced net ionic equation.

· Write the
overall single-displacement reaction.

· Identify the
reducing agent.

· Identify the
oxidizing agent.

For the
Second Chemical Reaction

· Write the
oxidation half-reaction.

· Write the
reduction half-reaction.

· Write the
balanced net ionic equation.

· Write the
overall single-displacement reaction.

· Identify the
reducing agent.

· Identify the
oxidizing agent.

For the
Third Chemical Reaction

· Write the
oxidation half-reaction.

· Write the
reduction half-reaction.

· Write the
balanced net ionic equation.

· Write the
overall single-displacement reaction.

· Identify the
reducing agent.

· Identify the
oxidizing agent.

For the
Fourth Chemical Reaction

· Write the
oxidation half-reaction.

· Write the
reduction half-reaction.

· Write the
balanced net ionic equation.

· Write the
overall single-displacement reaction.

· Identify the
reducing agent.

· Identify the
oxidizing agent.
