Chemistry: An Atoms Focused Approach
Chapter 1
Matter - Answer Everything in the universe that has mass (m)
Solid - Answer Definite volume and shape
Liquid - Answer Definite volume but not a definite shape
Gas (vapor) - Answer Neither definite volume or shape
Atoms - Answer Tiny building blocks
Molecules - Answer Groups of atoms held together in a characteristic pattern and
proportion
Chemical bonds - Answer What holds atoms together
Sublimation - Answer Solid to gas
Deposition - Answer Gas to solid
Energy - Answer The ability to do work
Work (w) - Answer The exertion of a force (F) through a distance (d)
Equation for work - Answer w = F x d
Heat - Answer Energy transfer where energy flows from a warm object to a cooler one
Chemical Reactions - Answer One or more substances converted into one or more
different substances
Potential Energy (PE) - Answer Energy stored in an object because of its position or
composition
Kinetic Energy (KE) - Answer Energy of motion
Law of Conservation of Energy - Answer Energy cannot be created or destroyed, only
converted
Kinetic Energy equation - Answer KD = 1/2mu^2
Symbol for speed - Answer u
Pure Substance - Answer matter that cannot be separated into simpler matter by a
physical process
, Chemistry: An Atoms Focused Approach
Chapter 1
Physical Process - Answer a transformation of a sample of matter, such as a change in
its physical state, that does not alter the chemical identity of any substance in the
sample
Element - Answer A pure substance that cannot be separated into simpler substances
by any chemical process
Compound - Answer A pure substance that is composed of two or more elements linked
together in fixed proportions and that can be broken down into those elements by some
chemical process
Chemical Formula - Answer a notation for representing the elemental composition of a
pure substance using the symbols of the elements; subscripts indicate the relative
number of atoms of each element in the substance
Law of Constant Composition - Answer the principle that all samples of a particular
compound always contain the same elements combined in the same proportions
Mixture - Answer a combination of pure substance in variable proportions in which the
individual substances retain their chemical identities and can be separated from one
another by a physical means
Homogeneous Mixture - Answer a mixture in which the components are distributed
uniformly throughout and have no visible boundaries or regions
Solution - Answer another name for a homogeneous mixture
Heterogeneous Mixture - Answer a mixture in which the components are not distributed
uniformly, so that the mixture contains distinct regions of different compositions
Immiscible Liquids - Answer combinations of liquids that are incapable of mixing with, or
dissolving in, each other
Distillation - Answer a process using evaporation and condensation to separate a
mixture of substances with different volatilities
Volatility - Answer a measure of how readily a substance vaporizes
Filtration - Answer a process for separating solid particles from a liquid or gaseous
sample by passing the sample through a porous material that retains the solid particles
