quiz 3 cards chemical reactions and electrons in atoms
solute = substance
solvent = water
symbol = aq
how to predict if a reaction will occur
results in neutralization and
production of salt and water
Symbols of states of matter
(g) gas (l) liquid (s) solid
is a reaction of Metal and Non-Metals
Oxidation is the loss of electrons
Reduction is the gain of electrons
Combining hydrocarbon and oxygen
produces carbon dioxide and water
combining simple substances
produces complex substances
reverse of synthesis
single replacement = one element replaces another in a compound
compund + element
Soluble compound that has Hydrogen as the positive ion
homogeneous mixture of a substance and water
compound that has hydroxide as an ion (OH)
a solid ionic compound seperating into its ions
Literally, to loosen. Used to describe the process in which one substance mixes with another. When a solid dissolves in a liquid, the particles that form the solid are released into solution.
a substance which forms ions in an aqueous solution
process which absorbs thermal (heat) energy.
term used to describe a reaction or process that releases energy in the form of heat.
not soluble in water (i.e. oil)
A substance that is formed as the result of a chemical reaction.
the initial substances in a chemical reaction.
dissolves in solution
The substance that is dissolved in a solution. For solutions of fluids, the solvent is present in greater amount than the solute.
The component of a solution that is present in the greatest amount. It is the substance in which the solute is dissolved.
labratory procedure used to determine the amount of a substance in a solution
a representation that shows the occupation of orbitals by electrons for a particular element.
energy is absorbed
Up to two electrons can occupy one orbital at a time.
the number of wave cycles or crests that pass through a stationary point in one second
the fraction of the elecromagnetic spectrum between between visible light and microwaves. invisable to the human eye
has no mass
travels @ 186,000 mi/s
features; wavelength, frequency, photons
electrons act as waves and particles tier paths are less predictable
Radiation is the emission and propagation of energy in the form of waves, rays or particles.
A band of colors, as seen in a rainbow, produced by separation of the components of light by their different degrees of refraction according to wavelength
sub levels of an atom called s,p,d,f
ultraviolet is spectrum of light between visable light and xray
the distance between adjacent wavecrests in a wave
electrons in discrete orbits
shells or energy levels
electrons have a dual nature
act as particles and waves
particles give off waves
calculated quantum mechanics models
