Catalyst
|
A substance that speeds up the rate of reaction without being changed/used up.
|
|
Catalytic Converter
|
Converts poisonous gases from the vehicles exhaust into less harmful substances.
|
|
Combustion
|
The fast reaction of a compound/element with oxygen gas to form an oxide to produce heat.
|
|
Decomposition
|
Chemical reaction where a compound is broken down into 2 or more elements/simpler compounds.
|
|
Double Replacement
|
2 ionic solutions that react to produce 2 other ionic compounds. Produces precipitate.
|
|
Neutralization (acid-base)
|
Chemical reaction that happens when an acid and a base react to make a salt and water.
|
|
Precipitate
|
Insoluble solid that forms from a solution.
|
|
Rate of Reaction
|
How fast products form in a chemical reaction.
|
|
Single Replacement
|
A reactive element and a compound react to produce another element and another compound.
|
|
Surface Area
|
Measure of the amount of area an object is exposed. Effects reaction rate.
|
|
Synthesis
|
Chemical reaction where 2 elements combine to produce a single product.
|
|
Temperature
|
The average energy of molecules. More energy: higher temperature.
|
|
Concentration
|
How many molecules exist in a certain volume. How much solute is dissolved in a solution. Higher concentration: Faster reactions.
|
|
Surface Area (chemical reactions)
|
When and where atoms compounds collide. More surface area: Faster reaction.
|
|
Enzymes
|
Biological catalyst.
|
|
Endothermic
|
Energy is absorbed. Ex. photosynthesis, melting, cooking of an egg, evaporation. |
|
Exothermic
|
Energy is released. Ex. water vapor condensing, rusting of iron, nuclear fission, spontaneous combustion. |
|
Kinetic Energy
|
Energy of a particle or an object due to it's motion.
|
|
Potential Energy.
|
Stored Energy.
