Preamble: Chemical Reactions
H2(g)
+ O2(g)
à H2O(l)
(the oxide of hydrogen)
Notice that
the reaction between an element and oxygen can be classified as both combination and combustion.
When a
compound burns the oxides of the elements that make up the compound are formed.
–When
you burned methane in the lab, for instance, the products formed are carbon
dioxide and water.
–The
reason those two oxides are formed is because methane is made up of carbon and
hydrogen.
CH4(g)
+ O2(g)
à CO2 + H2O(l)
3. Ion-exchange/double displacement
(replacement)/metathesis/precipitation reaction
Salt
solution 1 + salt solution 2 à precipitate of insoluble salt + solution of other salt
–As
you know by now, for the above reaction to occur, one of the products has to be
insoluble.
