What is Atoms and/or molecules combine to form a new compound
100
Decomposition reaction
What is The reverse of synthesis, a process whereby molecules are decomposed, often by the use of heat
100
Neutralization reaction
What is Protons are transferred from an acid to a base
100
Amphoteric
What is Can both accept and donate protons
100
Redox reactions
What is Net transfer of electrons; the species that loses electrons is oxidized, and the species that gains electrons is reduced.
200
Evidence of chemical change
What is 1. Production of heat or light
2. Formation of a gas
3. Formation of a precipitate
4. Color change
200
Endothermic
What is Net gain of energy; heat is absorbed
200
Exothermic
What is Net loss of energy; heat is released
200
Galvanic Cell
What is Redox reactions that generate electrical current; oxidation occurs at the anode, and reduction occurs at the cathode
200
Rate determining step
What is slowest step of the reaction
300
Catalysts
What is Increase the rate of the chemical reaction. Are used in the first step and produced in the last step.
300
Combustion reaction
What is Reaction is when oxygen combines with another compound to form water and carbon dioxide.
300
Synthesis reaction
What is Reaction is when two or more simple compounds combine to form a more complicated one.
300
Decomposition reaction
What is
Reaction where a complex molecule breaks down to make simpler ones
300
Single replacement reaction
What is
Reaction where one element trades places with another element in a compound.
400
Double replacement reaction
What is Reaction where the anions and cations of two different molecules switch places, forming two entirely different compounds.
400
Reaction rates depends on
What is 1. reactant concentrations
2. temperature
3. surface area
4. environmental factors
400
Rate law
What is k[A]^m [B]^n
400
Rate constant (k)
What is 1. the proportionality constant in the rate law
2. depends on temperature
3. units vary
400
Collision model
What is Elementary reactions are mediated
by collisions between molecules. Only collisions having sufficient energy and proper relative orientation of reactants lead to products.
500
Rate-limiting step
What is slowest elementary step
500
Network bonds
What is atoms held in a lattice of covalent bonds. electrons are localized and cant move.
500
Hydrogen bonding
What is hydrogen bonds to an extremely electronegative element f,o,n
500
Density for H2O
What is
denser as liquid because as a solid it makes a crystal structure
500
Dipole-dipole
What is
between neutral polar molecules molecules with greater polarity will have greater dip dip attraction. gas or liquid at room temp
