Chem 103 Exam 1
% accuracy - ANS-actual/concept x a hundred
% mistakes - ANS-commonplace-experimental/well-known x a hundred
1 L - ANS-a thousand mL
1 mL - ANS-zero.001 L
1 mol - ANS-6.022x10^23
As the atomic quantity increases in organization a - ANS-the chemical response will become
greater lively
Atomic mass unit - ANS-used to specific relative masses of atoms
12
6C
relative mass of 12 u
Atoms get bigger as - ANS-you go down the organization
-large cations release (donate) electrons extra without difficulty than smaller cations.
Atoms get smaller - ANS-as you pass across the duration left to right
Ball and stick model - ANS-Each detail is represented by means of a different colored ball
Carbon - ANS-Black
Centi - ANS-c
1/100 x basic unit
10^-2 x basic unit
Chemical Changes of be counted - ANS--Chemical modifications aren't constantly reversible.
-Chemical adjustments are constantly followed by means of a alternate in composition. Atoms
are converting partners.
-New sorts of matter are being created, O2 + 2H2 → 2H2O
Examples of chemical changes are the burning of paper and the fizzing of a combination of
vinegar and baking soda.
, Chemical Properties of Matter - ANS--Chemical houses may be determined or measured
simplest when the composition of count is changed.
Examples of chemical residences are flammability and the ability to react (e.G. Whilst vinegar
and baking soda are mixed). Atoms need to exchange companions.
Chemical View of the Atom - ANS--Nucleus is the center containing protons (+) and neutrons
(o). Electrons (-) are at the out of doors.
-Atomic wide variety = quantity of protons, which defines element.
-Atomic mass = mass of protons and mass of neutrons.
-Number of electrons = number of protons in neutral atom.
-Neutron mass = proton + electron.
Compound Formulas - ANS-A compound formulation includes the symbols of the elements
determined in the compound. Each elemental image represents one atom of the detail. If more
than one atom is represented, a subscript following the fundamental image is used.
Compounds - ANS--Compounds are pure substances that are made from atoms bonded to form
heteroatomic molecules or person (ions) of or greater exceptional kinds of atoms.
Examples: natural water made up of heteropolyatomic molecules and table salt made up of
sodium ions and chlorine ions. Technically, Ionic compounds are not molecules.
Dalton Atomic Particulate Model Of Matter - ANS--All rely is made of tiny particles known as
atoms.
-Unique varieties of atoms are referred to as factors.
-Molecules are collections of bonded atoms.
-Compound is fashionable term that consists of molecules, atoms and ions (atoms not having
normal wide variety electrons).
-Compounds have a set ratio of atoms.
-Chemical reactions do no longer create or damage atoms.
-Chemical reactions can create or damage compounds.
Deci - ANS-d

10^-1 x fundamental unit
Democritus (Greek, 460-370 BC) - ANS-First man or woman whose writings cautioned,
-based totally most effective on good judgment, that atoms in which the
foundation of matter.
-Atoms comes from the word 'atomos'
method "no reduce".
-Democritus stated there have been specific kinds of atoms.
