5 Reaction Types
Chemical reactions in which two or more substances react to produce a single product
What is a Combination reaction?
shorthand for chemical reactions using basic symbols and words
what is the word equation?
occurs because of the collision of gas particles with the walls of their container
What is gas pressure?
bonds between atoms, can be ionic, covalent, or metallic
What is a Intramolecular force?
can not create or destroy matter
what is the law of conservation of mass?
Oxygen combines with a substance and releases energy in the form of heat and light
what is a combustion reaction?
convert the words into all chemical symbols
what is a skeletal equation?
measure of the average kinetic energy of the particles
What is Temperature?
weak attractions between molecules
What is an intermolecular force?
number to count very small things
what is the mole?
single compound breaks down into two or more elements or new compounds
What is a decomposition reaction?
Lowest ratio between elements in a compound
what is the empirical formula?
as temperature goes down, particle slow down. All motion with theoretically stop at
What is absolute zero?
weak forces that result from temporary shifts in the density of electrons in the electron cloud
What is a dispersion force?
compound with water bound into the crystal lattice
what is a hydrate?
atom of one element replaces the atom of another element in a compound
what is a single replacement reaction?
mass of the elements and compounds to find the percent
what is percent composition?
as gas particles flow past one another, lighter particles travel more quickly
What is diffusion?
Attractions between oppositely charged regions of polar molecules
what are dipole-dipole forces?
take the shape of the container with a fixed volume
What is a liquid?
exchange of ions between two compounds precipitate - solid produced during a chemical reaction in a solution
what is a double-replacement reaction
actual yield/theoretical yield*100
What is percent yield?
the escape of gas through a tiny hole
What is effusion?
special type of dipole-dipole attraction that occurs with molecules containing H + either F,O, or N
What is a hydrogen bond?
a solid whose atoms, ions, or molecules are arranged in an orderly, geometric, three dimensional structure (lattice)
What is a crystalline solid?
