chemical formula - CORRECT ANSWER-A combination of chemical symbols and numbers to represent a
substance
chemical equation - CORRECT ANSWER-A representation of a chemical reaction that uses symbols to
show the relationship between the reactants and the products
,chromatography - CORRECT ANSWER-A technique that is used to separate the components of a
mixture based on the tendency of each component to travel or be drawn across the surface of another
material.
filtration - CORRECT ANSWER-A process that separates materials based on the size of their particles.
distillation - CORRECT ANSWER-A process used to separate dissolved solids from a liquid, which is
boiled to produce a vapor that is then condensed into a liquid
crystallization - CORRECT ANSWER-A separation technique that produces pure solid particles of a
substance from a solution that contains the dissolved substance.
leibig condenser - CORRECT ANSWER-Glassware used to condense water vapour, that consists of two
tubes one inside the other with space between for circulation of water.
element - CORRECT ANSWER-A pure substance made of only one kind of atom
atom - CORRECT ANSWER-the smallest component of an element having the chemical properties of
the element
periodic table - CORRECT ANSWER-a table of the chemical elements arranged in order of atomic
number, usually in rows, so that elements with similar atomic structure (and hence similar chemical
properties) appear in vertical columns.
compound - CORRECT ANSWER-A substance made up of atoms of two or more different elements
joined by chemical bonds
electron - CORRECT ANSWER-A tiny, negatively charged particle that moves around the nucleus of an
atom.
, nucleus - CORRECT ANSWER-A region that is located at the centre of an atom and contains most of the
atom's mass (protons and neutrons)
proton - CORRECT ANSWER-A subatomic particle that has a positive charge and that is found in the
nucleus of an atom
neutron - CORRECT ANSWER-A subatomic particle that has no charge and that is found in the nucleus
of an atom
atomic number - CORRECT ANSWER-The number of protons in the nucleus of an atom
atomic mass - CORRECT ANSWER-The average mass of all the isotopes of an element
mixture - CORRECT ANSWER-A combination of two or more substances that are *not* chemically
combined
chemical reaction - CORRECT ANSWER-the process by which one or more substances change to
produce one or more different substances
mass - CORRECT ANSWER-A measure of the amount of matter in an object
(g) - CORRECT ANSWER-indicates that a substance in a chemical equation is a gas
(s) - CORRECT ANSWER-indicates that a substance in a chemical equation is a solid
(aq) - CORRECT ANSWER-indicates that a substance in a chemical equation is dissolved in solution
(l) - CORRECT ANSWER-indicates that a substance in a chemical equation is a liquid
