QuestionAnswer
Alpha Partical Subtracts
Beta Partical Adds
Second Law of Thermodynamics In spontaneous process there is an increase in the entropy of the universe
Third Law of Thermodynamics The entropy of a perfect crystal at 0
Electrolysis Forcing a current through a cell to drive a non spontaneous reaction to occur
Irreversible Process System must take another path to return to its natural state
Gibbs Free Energy Change G= Change H- (T) Change S and Change G= Change G final- Change G Initial
Electrochemistry Study of relationships between electricity and chemical reactions
Oxidation Loss of electrons
Reduction Gain of electrons
Voltaic Cell Use of electricity from spontaneous redox reaction to generate electricity by transfer of electron through external pathway
Anode Oxidation
Cathode Reduction
Ecell Ecell= Cathode- Anode
Salt Bridge Allows for passage on ions to maintain electrical neutrality
Cell Potential Driving force for electron flow also EMF or Electromotive Force
Battery Voltaic cell or series of voltaic cells
Fuel Cells Voltaic cell with constant potential because reactants are constantly added
Corrosion Natural occurring oxidation of metals
Nucleons Subatomic particles

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
