Types of Reactions
Potpourri
Rates of Reaction
100
The electrons in the outer-most level of an atom.
What are valence electrons?
100
The attractive force that holds at least two atoms together.
What is a chemical bond?
100
This type of reaction is when oxygen combines with another compound to form water and carbon dioxide
What is Combustion?
100
These are the signs of a chemical reaction
What is a temp change, color change, bubbles, precipitate?
100
An increased reaction rate will occur with what kind of concentration?
What is a higher concentration?
200
This is the number of electrons in an atom's outer shell, making it very stable (NOT the first shell).
What is 8?
200
This bond forms from the attraction between oppositely charged atoms.
What is an ionic bond?
200
This type of reaction is when two or more simple compounds combine to form a more complicated one
What is a synthesis reaction?
200
Balance this equation: Fe+Cl2 --> FeCl3
What is 2Fe + 3Cl2 --> 2FeCl3?
200
This temperature will DECREASE the rate of reaction.
What is low temperature?
300
Charged particles that form when one or more valence electrons transfer from one atom to another.
What is an ion?
300
This bond forms when two (or more) atoms share electrons.
What is a covalent bond?
300
This reaction is the opposite of a synthesis reaction - a complex molecule breaks down to make simpler ones
What is a decomposition reaction?
300
The pH of a Base.
What is greater than 7?
300
This surface area (smaller or larger) will INCREASE the reaction rate.
What is smaller?
400
A negatively charged atom that occurs when an atom gains an electron.
What is an anion?
400
This type of element forms covalent bonds.
What are nonmetals?
400
The type of reaction when one element trades places with another element in a compound.
What is a single replacement reaction?
400
This type of reaction needs energy (heat) to be brought in.
What is endothermic?
400
This is a compound that increased the reaction rate but does not participate chemically.
What is a catalyst?
500
A model that shows only the valence electrons in an atom.
What is an electron dot diagram?
500
The cation in an ionic bond is usually this type of element.
What is a metal?
500
This reaction is when the anions and cations of two different molecules switch places, forming two entirely different compounds
What is double replacement reaction?
500
The number placed in front of an atom or compound.
What is a coefficient?
500
When a liquid is poured into another liquid and something is formed.
What is a precipitate?
