Unit 5 Test Flashcards
What usually results from a double replacement reaction
A solid participate a gas or water
What is a synthesis reaction
A chemical reaction where two or more substances react to produce a single product
A+B=AB
What is a decomposition reaction
One reactant breaking up into several products
AB—> A+B
What are typically used in decomposition reactions
Catalysts because a decomposition reaction requires a lot of energy and catalyst help to speed up the reaction
For a decomposition reaction how what would you balance the equation of sodium hydrogen carbonate
Your first need the metal carbonates then carbon dioxide, then water
What is a single replacement reaction
When an element replaces another element in a compound
In a single replacement reaction metals replace
Metals
A single replacement nonmetals replace
Non metals
In a single replacement reaction how do we know whether or not a nonmetal will take a reaction with a new metal
If it is higher up on the activity series
What is a combustion reaction
These reactions involve the burning of hydrocarbons during combustion oxygen is always one of the reactants
What are hydrocarbons
Compounds that contain only hydrogen and carbon
What is a complete combustion reaction
When the hydrocarbon is burned in plenty of oxygen
What are the two products in a complete combustion reaction
Carbon dioxide and water
What is an incomplete combustion reaction
When the amount of oxygen is limited
Methane
CH4
Ethane
C2H6
Propane
C3H8
Butane
