Mixture with uniform density throughout and no distinguishable coponents. - ANSHomogeneous
Mixture
Mixture in which the components are readily distinguished. - ANSHeterogeneous Mixture
A change in which the checmical composition of a substance remains the same. - ANSPhysical
Change
A change in which the chemical bonds are broken and reformed to create a new and different
substance. - ANSChemical Change
The simplest of substances and is represented by a specific letter or combinations of letters. -
ANSElement
Combinations of eleements in whole number ratios. - ANSCompounds
Mass cannot be created or destroyed during a chemical reaction. - ANSLaw of Conservation of
Mass
The breaking of bonds and the reforming of new bonds to create new chemical compounds with
different chemical forumulas and different chemical properties. - ANSChemical Reaction
syntehesis, decomposition, combusion, single replacement, double replacement - ANSFive
main types of chemical reactions.
Two elements combine to form a product. - ANSSyntehsis Reaction
The breaking of a compound into component parts. - ANSDecomposition Reaction
The reaction of a compound or element with oxygen. In the combusiton of a hydrocarbon
carbon dioxide and water are produced. - ANSCombustion Reaction
Reaction involoving ionic compounds. The reactivity of the ionic compounds determines
whether the reaction will take place or not. Can be single replacement or double replacement
reaction. - ANSReplacement Reactions
Reaction between a more active metal reacting with an ionic compound containing a less active
metal to produce a new compound ex. copper wire reacting with aqueous silver nitrate. -
