Unit 5: Chemical Reactions
Types:
Single Replacement
an element replaces another element in a compound
reactivity
Double Replacement
an element from one compound replaces and element in another
solubility
Combustion
elements reacting with oxygen
Decomposition
compound breaking down to smaller elements or compounds
opposite of combination
carbonates, hydroxides
Combination
elements reacting to make a compound
2 element compound = binary compound
hydroxides, acids, carbonates
Formulas:
metal carbonate
meta oxide + CO2
CO3-
metal hydroxide
metal oxide + H2O
OH-
non-metal hydroxide
non-metal oxide + H2O
H2__xOx
