Chemistry Level 3 Marking Period 1

QuestionAnswer
What are two or more substances physically combined called? mixture
kilo- 1000 x basic unit
hecto 100 x basic unit
solid the state of matter that has the lowest energy
solid the phase in which atoms are closely packed together and can only vibrate
liquid the state of matter that has a definite volume but an indefinite shape
liquid the phase in which atoms and molecules can move freely in two dimensions
gas the phase in which atoms and molecules are far apart and move freely in 3-D
gas the state of matter that has both an indefinite shape and volume
plasma the state of matter with the highest energy
plasma the state in which most of the matter in the universe can be found
gas the state of matter that is common on earth and can be compressed easily
surface tension the attraction among particles in liquids
freezing the change of state from a liquid to a solid
freezing point the temperature at which a liquid changes to a solid
melting the change of state from a solid to a liquid
melting point the temperature at which a solid changes to a liquid
vaporization includes both boiling and evaporation
boiling the change from a liquid to a gas that occurs throughout the liquid
evaporation a change from liquid to gas; it occurs only on the liquid's surface
boiling point the temperature at which a liquid changes to a gas
condensation the change from a gas to a liquid
compound two or more elements chemically combined in a definite proportion
mixture Two or more substances that are physically combined
physical change methods used to separate mixtures
homogeneous mixture A mixture that appears the same throughout
heterogeneous mixture A mixture in which separate substances can be seen
solution a homogeneous mixture that appears to have one state of matter
suspension a heterogeneous mixture in which particles settle out by themselves
colloid A homogeneous mixture that is usually white and opaque; does not settle
physical properties Characteristics observed without changing the substance
chemical properties characteristics of how substances react with one another chemical properties
changes of state are ALL physical changes
mixtures substances physically combined in no definite proportion
compound two or more elements chemically combined
element contains atoms of only one type; these are found on the periodic table
atom the smallest piece of an element with all the properties of that element
molecule smallest piece of a compound with all the properties of that compound
chemical symbol the shorthand way scientists write an element's name
chemical formula The shorthand way scientists write a compound
chemical formula Tells what elements and how many atoms of each are in a compound
reactants The substances that come together to react in a chemical reaction
products The new substances that are formed in a chemical reaction
reactants These are shown to the left of the arrow in a chemical equation
products These are shown to the right of the arrow in a chemical equation
atoms are made of protons, neutrons and electrons
proton the massive, positively charged particle in the nucleus of an atom
neutron the massive uncharged particle that is found in the nucleus of an atom
electron negatively charged particle with little mass found outside the nucleus
filtration method used in the foul water lab that removed large solid particles
saturated solution solution that has the maximum amount of solute possible
unsaturated solution solution with less than the maximum amount of solute
supersaturated solution A solution with more than the maximum amount of solute
ions Charged atoms;they have different numbers of protons and electrons
acids substances that contain an excess of H+ ions
bases substances that contain an excess of OH- ions
acids pH less than 7
bases pH more than 7
pH a measure of the concentration of H+ ions
