What is dimensional analysis? - Answer A way to analyze and solve problems using the units,
or dimensions, of the measurements
What is the formula for density? - Answer D=m/v
what is an atom? - Answer the basic unit of a chemical element.
What is a molecule? - Answer A group of atoms bonded together, representing the smallest
fundamental unit of a chemical compound that cab take part in a chemical reaction
What is an element? - Answer a Substance that contains only ONE type of atom.
What is matter? - Answer Anything that has mass and takes up space
What is a mixture? - Answer a substance made by mixing other substances together.
What is a solution? - Answer A homogeneous mixture of two or more substances
What is a homogeneous mixture? - Answer a mixture that is the same throughout ( has the
same proportions of its components throughout any given sample)
What is a heterogeneous mixture? - Answer combination of 2 or more pure substances in
which the original retain their chemical properties
,what is a solid - Answer A state of matter that has a definite shape and volume
What is a liquid? - Answer A state of matter that has a definite volume but no definite shape.
What is a gas? - Answer A state of matter with no definite shape or volume
what is a chemical property? - Answer the ability of a substance to undergo a specific chemical
change
What is a physical property? - Answer a quality or condition of a substance that can be
observed or measured without changing the substance's composition
What is a chemical change? - Answer A change in matter that produces one or more new
substances
What is a physical change? - Answer A change in which the form or appearance changes, but
no new substances are formed
What are the different forms of energy? - Answer kinetic energy and potential energy
What is kenetic energy? - Answer energy of motion (movement)
What is potential energy? - Answer energy that is stored
What is an electron? - Answer A subatomic particle that has a negative charge
What is a proton? - Answer positively charged subatomic particle
What is an neutron? - Answer Neutrally charged particles that are in the nucleus
What is the law of constant composition in chemical calculations? - Answer The law of
constant composition says that, in any particular chemical compound, all samples of that
compound will be made up of the same elements in the same proportion or ratio. For example,
any water molecule is always made up of two hydrogen atoms and one oxygen atom in a ratio.
What is an ionic bond? - Answer A chemical bond that's formed when an atom transfers and
electron to another Atom
, What is a covalent bond? - Answer A chemical bond formed when two or atoms share
electrons.
Where are metals on the periodic table? - Answer Left side and middle
Where are nonmetals located on the periodic table? - Answer right of staircase
Where are metalloids located on the periodic table? - Answer in the "staircase"
What is an ionic compounds - Answer compounds composed of cations and anions
What is a molecular compound? - Answer a compound composed of molecules
What is an Atomic Element? - Answer elements whose particles are single atoms
What is a diatomic element? - Answer Any element that requires a bond between another
atom of itself.
What is a ionic compound? - Answer Compound composed of electrically charged ions that
are present in fixed proportions and are arranged in a regular, geometric pattern
Calculate molar mass - Answer find the number of grams in each elements, find the number of
grams of each element in one mole, and add together
To convert from grams to moles - Answer divide by molar mass
Convert between number of atoms and moles (Avogadro number) - Answer 1 mole = 6.022 ×
10 23
What is a endothermic reaction? - Answer A reaction that ABSORBS energy in the form of heat
What is a exothermic reaction? - Answer A reaction that releases energy in the form of heat
what is single displacement? - Answer a reaction in which one element replaces another in a
compound...A+BC (arrow) AC+B
