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.
4. A variety of reactions
involving acids, namely:
