|
Chemical Equation |
A representation of a chemical reaction; the formulas of the reactants are connected by an arrow with the formulas of the products. |
|
|
Catalyst |
A substance that speeds up the reaction but is not used up in the reaction |
|
|
Coefficients |
Small whole numbers that are placed in front of the formulas in an equation to balance it. |
|
|
Balanced Equation |
Where each side of the equation has the same number of atoms of each element and mass is conserved |
|
|
Combination Reaction |
A chemical change in wich two or more substances react to form a single new substance |
|
|
Single-replacement Reaction |
A chemical change in which one element replaces a second element in a compound |
|
|
Activity Series |
Lists metals in order of decreasing reactivity |
|
|
Complete Ionic Equation |
An equation that show dissolved ionic compounds as discarded ionic compounds as dissociative free ions |
|
|
Spectator Ion |
An ion that appears on both sides of an equation but is not directly involved in the reaction |
|
|
Net Ionic Equation |
An equation for a reaction in solution that shows only those particles that are directly involved in the chemical change |
|
|
How do you write a skeleton equation? |
Write the chemical formulas for the reactants to the left of the yeilds sign and the formulas for the products to the right |
|
|
What are the steps for writing and balancng a chemical equation? |
First write the skeleton equation. Then use coefficients to balance the equation so that it obeys the law of conservation of mass |
|
|
What are the five general types of reaction? |
Combination, decomposition, single-replacement, double-replacement, and combustion |
|
|
What does a net ionic equation show? |
Only those particles involved in the reaction and is balanced with respect to both mass and charge |
|
|
How can you predict the formation of a precipitate in a double-replacement reaction? |
By using the general rules for solubility of ionic compounds, you can predict the formation of a precipitate |
|
|
Skeleton Equation |
A chemical equation that does not indicate the relative amounts of the reactants and products |
|
|
Decomposition Reaction |
A chemical change where a single compound breaks down into two or more simpler products |
|
|
Double-replacement Reaction |
A chemical change involving an exchange of positive ions between two compounds |
|
|
Combustion Reaction |
A chemical change where an element or a copound reacts with oxygen, often producing energy in the form of heat and light |
