Chemical Reactions (slides) Flashcards
Word equations:
describes a chemical reaction using the names of the reactants and products
Chemical equation:
describes a chemical reaction using the chemical formulas of the reactants and products
(States of Matter) s:
solid
(states of matter) l:
liquid
(States of matter) g:
gas
State of matter: (aq)
aqueous solution (dissolved in water)
Symbols used in CEq: ->
yields
Symbols used in CEq: -> <-
indicates a reversible reaction
Symbols used in CEq: |/ arrow down
used in place of (s), but only used in product side to indicate a precipitate
Symbols used in CEq: ^| arrow up
used in place of (g), but only used in product side to indicate a gaseous product
Condition Symbols: arrow with rtriangle
reactants are heated
Condition Symbols: arrow with 2atm on top
pressure at which reaction is carried out
Condition Symbols: arrow with temp on top
temperature at which reaction is carried out
Condition Symbols: arrow with a catalyst on top
formula of a catalyst used to alter the rate of the reaction
Diatomic Elements:
H, N, O, F, Cl, Br, I
Elemental Metals are always:
solid (s) except mercury
Acids are always:
aqueous (aq)
Rules for writing formulas: Ionic Compound
use charges to determine the formula
Rules for wrting formulas: Covalent Compounds (molecular compounds) :
use prefixes to determine the formula
