| exothermic reaction | a chemical reaction in which energy is released to the surroundings as heat
🗑
|
||||
| endothermic reaction | a chemical reaction that requires energy input
🗑
|

| chemical equation | a representation of a chemical reaction that uses symbols to show the relationship between the reactants and the products
🗑
|
||||
| mole ratio | the relative number of moles of the substances required to produce a given amount of product in a chemical reaction
🗑
|
||||
| synthesis reaction | a reaction in which two or more substances combine to form a new compound
🗑
|
||||
| decomposition reaction | a reaction in which a single compound breaks down to form two or more simpler substances
🗑

||||
| free radical | an atom or a group of atoms that has one unpaired electron
🗑
|
||||
| oxidation-reduction reaction | any chemical change in which one species is oxidized (loses electrons) and another species is reduced (gains electrons); also called redox reaction

||||
| catalyst | a substance that changes the rate of a chemical reaction without being consumed or changed significantly
🗑
|
||||
| enzyme | a molecule, either protein or RNA, that acts as a catalyst in biochemical reactions (241)
🗑
|
||||
| substrate | a part, substance, or element that lies beneath and supports another part, substance, or element; the reactant in reactions catalyzed by enzymes
🗑
|
||||
| chemical equilibrium | a state of balance in which the rate of a forward reaction equals the rate of the reverse reaction and the concentrations of products and reactants remain unchanged
🗑

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.
