Answer all of the questions below. If you do not know an answer enter CNA. However, it will help me the most if you answer each question with your best intuition/idea about what would be a reasonable answer.

The BCE must be completed before class starts, for this BCE class has already met. It will not count towards your BCE total. NOTE: If class has not started and you receive this message, go ahead and do the BCE, I'll still count it.

Before answering any questions open and play this movie (the movie will open in a new browser window). The movie depicts how four metal strips (labeled A, B, C and D) react when added to different solutions of the metal ions (A⁺², B⁺, C⁺² and D⁺³). After watching the video, leave the screen open so you can consult the experimental results.

1a. Identify the metal ion (A⁺², B⁺, C⁺² or D⁺³) that is the most reactive.

b) Describe the evidence that supports your claim of the identity of the most reactive metal ion.

c) Identify the metal (A, B, C and D) that is the least reactive.

d) Describe the evidence that supports your claim of the identity of the least reactive metal.

e) What is the relationship between the identity of the most reactive metal ion and the least reactive metal?

f) Write a balanced chemical equation that relates the most reactive metal ion to the least reactive metal. (Remember a balanced chemical equation must be mass balanced and charge balanced.)

2a. Identify the metal ion (A⁺², B⁺, C⁺² or D⁺³) that is the least reactive.

b) Describe the evidence that supports your claim of the identity of the least reactive metal ion.

c) Identify the metal (A, B, C and D) that is the most reactive.

d) Describe the evidence that supports your claim of the identity of the most reactive metal.

e) What is the relationship between the identity of the most reactive metal ion and the least reactive metal?

f) Write a balanced chemical equation that relates the most reactive metal io n to the least reactive metal. (Remember a balanced chemical equation must be mass balanced and charge balanced.)

3. Complete the following table (NOTE: List the four metal ions fro m most reactive (top) to least reactive (bottom) in the table, and list the four metals from least reactive (top) to most reactive (bottom). In the table below enter metal ions using the following format: for an ion like D⁺³ as D^+3.

Metal Ions	+ # of electrons	-->	Metals
	+ e^-	-->
	+ e^-	-->
	+ e^-	-->
	+ e^-	-->

4. Is there anything about the questions that you feel you do not understand? List your concerns/questions.

5. If there is one question you would like to have answered in lecture, what would that question be?
