electrolytic cells form a thin coating of metal on an object
electroplating
chemical reaction produces electricity
voltaic cell
reaction that occurs without continuing outside help
spontaneous reaction
reaction proceeds either direction
reversible reaction
electricity produces a chemical reaction
electrolytic cell
produces electricity and is continually replenished from outside source
fuel cell
sour taste
acid
bitter taste, slippery feel
base
formed by an acid and base
salt
substances that undergo chemical change; on left side
reactants
new substance produced by the reaction; on right side
products
energy is absorbed
endothermic reaction
energy is released
exothermic reaction
gains electrons
reduction
loses electrons
oxidation
where oxidation occurs
anode
where reduction occurs
cathode
chemical equation that has same number of atoms of each element on both sides
balanced equation
kinetic energy that is necessary for molecules to react
activation energy
2 or more substances combine to form a new substance
combination reaction
compounds break down
decomposition
study of compounds containing carbon
organic chemistry
represents concentration of hydrogen
pH scale
7.1-14 on pH scale
base range
0-6.9 on pH scale
acid range
substance that changes color depending on pH; example litmus
acid-base indicator
one or more hydrogen atoms are replaced by -OH groups
alcohol
single bond between carbon atoms
alkane
one or more double bonds between carbon atoms
alkene
one or more triple bonds between carbon atoms
alkyne
ring of carbon atoms
aromatic
contain the group -COOH
carboxylic
contain -COO- group
ester
one or more hydrogen atoms replaced by halogen atoms (CI, Br, or I)
haloalkanes
loses electrons= oxidation
gains electrons- reduction
LEO says GER
electrons are transferred between atoms
redox reaction
related energy gained by a system to the energy lost by its surroundings
first law of thermodynamics
an element in a compound is replaced by another element
single-displacement reaction
2 compounds exchange atoms or ions
double-displacement reaction
system at equilibrium is disturbed, the system will react to partially offset the disturbance
le chateliers principle
when a strong acid base react to produce water and a salt
neutralization
