|---|---|---|---|---|---|
| electricity | process of pushing electrons through a circuit
🗑
|
||||
| electrochemistry | study of spontaneous chemical reactions to produce electricity and the use of electricity to drive nonspontaneous reactions
🗑
|
||||
| electrochemical cell | device in which an electric current is either produced by a spontaneous chemical reaction or used to bring about a nonspontaneous reaction
🗑
|
||||
| electrolytic cell | an electrochemical cell where electrolysis occurs (current is used to drive nonspontaneous reaction)
🗑
|
||||
| chemical kinetics | study of rates of chemical reactions
🗑
|
||||
| rate of reaction | a positive quantity that tells us how the concentrations of a reactant or product changes with time
🗑
|
||||
| rate law | expression for reaction rate in terms of concentrations of a species at any instant
🗑
|
||||
| reaction mechanism | description of a path, or a sequence of steps, by which a reaction might occur at the molecular level
🗑
|
||||
| kinetic energy | at higher temperatures there are more molecules with high kinetic energy
🗑
|
||||
| nuclear chemistry | changes that occur with the nucleus
🗑
|
||||
| nuclear fission | fragmentation of large nuclei into smaller nuclei
🗑
|
||||
| nuclear fusion | merging of small nuclei into larger ones
🗑
|
||||
| nuclear decay | spontaneous particle break up due to cramped space of protons in an atom. The repulsion between protons overcomes the force holding the nucleus together
🗑
|
||||
| isomers | different compounds that have the same molecular formula
🗑
|
||||
| stereoisomer | atoms have same partners but arranged differently in space
🗑
|
||||
| structural isomer | atoms connected to different partners
🗑
|
||||
| ionization isomer | ligand and anion in one isomer switch positions to form other isomer
🗑
|
||||
| hydrate isomer | ionization isomer where water is one of the ligands whose position is different in different isomers
🗑
|
||||
| linkage isomer | ligands in complex have more than one atom that can bond to the central metal ion; different atoms in isomer is actually bonded to central metal ion
🗑
|
||||
| coordination isomer | both anion and cation are complexes and ligand in anionic complex in one isomer exchange with a ligand in the cationic complex
🗑
|
||||
| geometrical isomer | atoms bonded to same neighbors but with different locations relative to each other
🗑
|
||||
| optical isomer | nonsuperimposable mirror images of each other
🗑
|
||||
| chiral complex | one that is not identical iwth its mirror image
🗑
|
||||
| achiral complex | one that is superimposable on its mirror image (not optical isomers)
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
