1. Using the Lecture, please check all that correctly applies for each row. There can be multiple answers (columns) for each row or no correct choices for a row.

Luigi Galvani

Alessandro Volta

Ben Grodski

Created the 1st battery

Shocked pithed frogs with static electricity, originally!

Argued that electricity was inherent to Biology

Proved the other Italian scientist incorrect

A Tall teacher from the 21st century

His name was given for Joule per Coulomb

Batteries or electrochemical cells that are spontaneous are/is named after

Developed the first value of energy

2. A Joule *

Is Force x Mass

Is Mass x Accerlation

Is Work x Mass

Is a expensive mineral that you find "in the rough"

Is Force x Distance

Is found on nutritional labels in the USA

3. Using my analogy of the waterfall, which of the following images would DEPICT a Voltaic cell with a Very High Voltage but a Very Small Amperage. *

4. TRUE or FALSE The potential difference in charge increases in a nerve cell as the sodium potassium pump creates an environment inside the nerve cell that has less positives than outside AND this potential difference provides the energy for the positive ions to rush into the nerve cell to create the electrical signal. *

True

False

5. Please check all that correctly applies for each row. There can be multiple answers (columns) for each row or no correct choices for a row. *

Voltage

Amperage

Joule

Potential difference of charge

Joule per Coulomb

Energy to move charges through a circuit

Measure of Spontaneaity

Coulombs per time

Amount of charge per second

Kg meter /sec^2

6. Rank the order of the following Halogens in order of increasing oxidation potential. *

1st

2nd

3rd

4th

F -

Cl -

Br -

I -

7. True Or False - Rusting is Metals becoming positive ions. *

True

False

8. If Fluorine has the greatest ability to reduce based on the standard reduction tables where would the chemical species on the same table be located that has the greatest ability to oxidize? *

Gold (Au)?

Upper Right of the Standard Reduction Table

Upper Left of the Standard Reduction Table

Lower Right of the Standard Reduction Table

Lower Left of the Standard Reduction Table

9. In the voltaic cell, the Cathode gets reduced BECAUSE reduction is the gaining of electrons. *

Here are the instructions on how to answer this type of True / False question.

T, T, CE

T, F

F, T

F, F

T, T

10. Given the following Voltaic Cell choose the correct chemical species for the descriptor: *

Mg+2

Al+3

Anode

Cathode

Chemical that gets oxidized

Chemical that gets reduced

11. Given the same voltaic cell in question 10 answer True or False for each statement *

True

False

The electrons or current moves Right to Left

The K+ ion in the salt bridge moves into the right cell to maintain electrical neutrality

Aluminum (Al) gets smaller as the Voltaic cell operates

The salt bridge allows electrons to flow threw it.

The Net Voltage of the Voltaic cell equals 0.71 volts

Based on the Net Voltage of the battery, this process is spontaneous
