| How do you write a word equation? | write the names of the reactants separated by a plus sign on the left of the arrow and the names of the products separated by a plus sign on the right
🗑
|
||||
| how do you write a skeleton equation? | write the formulas of the reactants to the left of the yields sign and the formulas of the products to the right
🗑
|
||||
| describe the steps in writing a balanced chemical equation | write the skeleton equation with the correct formulas of the reactants on the left and the correct formulas of the products on the right, then balance the equation using coefficients so that it obeys the law of conservation of mass
🗑
|
||||
| five types of chemical reactions | combination, decomposition, single-replacement, double-replacement, and combustion
🗑
|
||||
| what are the keys to predicting the products of the five general types of reactions? | the number of elements and/or compunds reacting
🗑
|
||||
| what are the three types of products that result from double-replacement reactions? | gas, precipitate, and molecular compound
🗑
|
||||
| what is a net ionic equation? | shows only those particles involved in the raction and is balanced with respect to both mass and charge
🗑
|
||||
| how can you predict the formation of a precipitate in a double-replacement reaction? | use the general rules for solubility of ionic compounds
🗑
|
||||
| what is the function of an arrow in a chemical equation? | the arrow separates the reactants from the products and indicates a reaction that progresses in a forward direction
🗑
|
||||
| what is the purpose of a catalyst | it speeds up a chemical reaction
🗑
|
||||
| what is a characteristic of every combination reaction? | a single product
🗑
|
||||
| what is a distinguishing feature of every decomposition reaction? | a single reactant
🗑
|
||||
| what substance is common to all combustion reactions? | oxygen
🗑
|
||||
| what is a spectator ion | an ion that does not participate in the reaction.

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.
