|---|---|---|---|---|---|
| Equations that show just the formulas of the reactants and products are called what? | skeleton equations
🗑
|
||||
| How do you write a skeleton equation? | first write the chemical formulas for the reactans to the left of the yields sign and then write the products to the right.
🗑
|
||||
| What is a catalyst? | a substance that speeds up the reaction but is not used up in the reaction.
🗑
|
||||
| What is a combination reaction? | a chemical change in which two or more substances react to form a single new substance.
🗑
|
||||
| What is a decomposition reaction? | a chemical change in which a single compound breaks down into two or more simpler products.
🗑
|
||||
| A chemical change in which one element replaces a second element in a compound is known as what? | single-replacment reaction
🗑
|
||||
| What is the activity series? | a list of metals in order os decreasing reactivity
🗑
|
||||
| A chamical change involving an exchange of positive ions between two compounds is know as what? | double-replacment reactions
🗑
|
||||
| Define: Combusyion reaction | a chemical change in which an element or a compound reacts with oxygen, often producing energy in the form of heat or light
🗑
|
||||
| What does a net equation show? | only those particles involved in the reaction and is balanced with respect to both mass and chanrge.
🗑
|
||||
| What is a specator ion? | an ion that appears on both sides of an equation and is not directly involved in the reaction
🗑
|
||||
| The net ionic equation is what? | the equation for a reaction in solution that shows only those particles that are directly involved in the chemical change.
🗑
|
||||
| How can you predict the formation of a precipitate in a double-replacement reaction? | by using the general rules of ionic compounds, you can predict the formation of a precipate
🗑
