basic chemistry Flashcards
define elements
elements can’t be broken down into simpler substances using simple chemical separation methods
define compounds
compounds are substance that contains 2 or more elements that are chemically bonded
define mixtures
mixture contains 2 or more substances that are physically combined without any chemical bonds
define molecules
molecules contains 2 or more same or different atoms that are chemically bonded
define atoms
atoms are the smallest particle in any element
state the purity of compounds and mixtures
compounds are pure substances with fixed ratios
mixtures are unpure substances with unfixed ratios
state the B.P and M.P of mixtures and compounds
compounds have fixed M.P and B.P
mixtures have unfixed M.P and B.P
state the differences between physical and chemical properties of compound and mixture
compounds have unique physical and chemical properties
mixtures have same properties as its components
state the differences between the separation techniques for compounds and mixtures
compounds can’t be easily separated by physical methods, only possible through chemical methods
mixtures can be easily separated using physical separation techniques
