Honors Chemistry Final Questions And Answers With
Verified Solutions
law of conservation of mass ANS the law that states that mass cannot be created or destroyed in ordinary
chemical and physical changes
law of definite proportions ANS the law that states a chemical compound always contains the same elements in
exactly the same proportions by weight or mass
law of multiple proportions ANS the law that states that when two elements combine to form two or more
compounds, the mass of one element that combines with a given mass of the other is in the ratio of small whole
numbers
atom ANS the smallest component of an element having the chemical properties of the element
nuclear forces ANS the interaction that binds protons and neutrons, protons and protons, and neutrons and
neutrons together in a nucleus
atomic number ANS the number of protons in the nucleus of an atom
isotope ANS an atom that has the same number of protons as other atoms of the same element do but that has a
different number of neutrons
mass number ANS the sum of the number of neutrons and protons that make up the nucleus of an atom
nuclide ANS An atom that is identified by the number of protons and neutrons in its nucleus
atomic mass unit ANS a unit of mass that describes the mass of an atom or molecule
average atomic mass ANS weighted average of the atomic masses for the isotopes of an element
mole ANS the SI base unit used to measure the amount of a substance whose number of particles is the same as
the number of atoms of carbon in exactly 12g of carbon-12
, Avogadro's number ANS used to find molecules. the number of atoms or molecules in one mole (6.022 x 10^23)
molar mass ANS the mass in grams of 1 mol of a substance
Electromagnetic radiation ANS A form of energy that exhibits wavelike behavior as it travels through space
Electromagnetic spectrum ANS All of the frequencies or wavelengths of electromagnetic radiation
Wavelength ANS The distance between corresponding points on adjacent waves
Frequency ANS the number of waves that pass a given point per second
Photoelectric effect ANS The emission of electrons from a metal when light shines on the metal
Quantum ANS The minimum amount of energy that can be gained or lost by an atom
Photon ANS A particle of electromagnetic radiation having zero mass and carrying a quantum of energy
Ground state ANS The lowest energy state of an atom
Excited state ANS A state in which an atom has a higher potential energy than it has in its ground state
Line-emission spectrum ANS A diagram or graph that indicates the degree to which a substance emits radiant
energy with respect to wavelength
Continuous spectrum ANS The emission of a continuous range of frequencies of electromagnetic radiation
Heisenberg uncertainty principle ANS It is impossible to know exactly both the velocity and the position of a
particle at the same time
