Chemistry 101 Unit 1
1 calorie - correct answerThe amount of heat energy required to increase the
temperature of one gram of water 1 degree C. Equal 4.184 (J)
1 kcal - correct answer1 Calorie= 1000 calories
2 theories used to describe acidity - correct answerArrhenius and bronsted lowry
3 basic components of the centrifuge - correct answerrotor motor drive shaft
3 types of centrifuge - correct answerhorizontal head, fixed angle, angle head
4 processes used to purify water - correct answerdistillation, deionization, reverse
osmosis, and filtration.
5 top elements of biological significance - correct answercarbon hydrogen oxygen
nitrogen phosphorus
ACID - correct answerAcid
Acids must be diluted by what? - correct answerSlowly adding water while mixing
ALK - correct answerAlkali
Alkali metal - correct answerdo not occur as free elements, because they are too
reactive. They are typically shiny metal and are so soft they can be cut with a butter
knife. They react very violently with air and water so they have to be stored under oil.
Alkaline earth metals - correct answer(Group IIA) less reactive than the alkali metals.
They do not have to be stored under oil, but do react with air, water and other elements
violently.
American Society for Testing and Materials (ASTM), - correct answervoluntary
consensus standards. Class A volumetric glassware is defined in ASTM standards
amphoteric - correct answera compound that can act as both a proton donor or proton
acceptor.
Analytical Chemistry - correct answerInvolves the analysis of matter to determine its
composition and quantity of each kind of matter that is present (Lab)
Analytical chemistry - correct answerinvolves the analysis of matter to determine its
composition and quantity of each kind of matter that is present.
,Anion - correct answerNegatively charged ion (Cl-)
anions are [ smaller or larger ] then parent atom - correct answerlarger
Atom - correct answerThe smallest unit of an element that retains the chemical
properties of that element
Atom: - correct answerThe smallest part of an element that retains the properties of that
element.
Atomic number - correct answerThe number of protons in the atom
Atomic size increases - correct answers from top to bottom but decreases from left to
right in the periodic table.
Atoms consist of three primary particles - correct answerElectrons, Protons, Neutrons
Atoms will gain, lose, or share electrons in order to... - correct answerAttain a more
stable energy state
Basic Units for heat energy: - correct answerCalorie or Joule
Biochemistry - correct answeris the study of life at the molecular level and processes
associated with life, such as reproduction, growth, and respiration.
Biochemistry - correct answerThe study of life at the molecular level
Biological Hazard - correct answerPossibility of exposure to infectious biological agents
Blow out - correct answerTo deliver the amount of fluid from a device by "blowing out"
(using a mechanical device or safety bulb) all the fluid contained in the pipet.
Bohr Theory - correct answerSurrounding each nucleus has a certain fixed energy
levels that could occupy electrons
Bronsted-Lowery (proton donor): - correct answerA compound that donates a hydrogen
ion or proton (H+), to another compound in a specific reaction is an acid
Bronsted-Lowery: (proton acceptor) - correct answerA compound that accepts a
hydrogen ion is a base (anything that accepts a proton)
Buffer solutions, - correct answerconsist of a mixture of a weak acid and its salt or a
weak base and its salt, are resistant to large pH changes upon the addition of acids or
bases.
CAP - correct answerCollege of American Pathologists
, Carbon group (Group IVA) - correct answerAll elements have 4 valence electrons.
Carbon forms 4 covalent bonds. Tin and lead form ions with either a +2 or a +4 charge.
Cation - correct answerPositively charged ion (H+)
Cations and anions must combine to give a formula with a net charge of - correct
answerzero. Positive charge should equal the negative subscript and vice versa.
cations are [ Larger or smaller ] then parent atom - correct answersmaller
CDC - correct answerDisease Control and Prevention
Centigrade (C) - correct answer0= freezing point of pure water
37= body temperature
100=boiling point of water
Centigrade to Fahrenheit - correct answerF=(1.8xC) + 32
Centigrade to Kelvin - correct answerK= C+ 273.15
centrifuge - correct answern instrument used to separate fractions of a mixture by
spinning the mixture al a high speed in a circular motion
Chemical bond - correct answerThe force of attraction between any two atoms in a
compound
Chemical Hazard - correct answerPossibility of exposure to harmful chemicals
Chemical properties - correct answerCharacteristics of a substance
Chemical reactions - correct answerA process of rearranging, removing, replacing, or
adding atoms to produce new substances
Chemistry - correct answerThe study of matter
CHP - correct answerChemical Hygiene Plan
class a fire - correct answerordinary combustible
class b fire - correct answerflammable gas and liquid
class c fire - correct answerelectrical
class d fire - correct answerreactive metals
