Double Replacement Chemical Reaction
Two types of atoms or groups exchange places to form two new compunds.
Example: HCl + NaOH --> NaCl + H2O
Note: If you use CHEMIX School for balancing
chemical reactions/equations
you must replace the arrow '-->' by '>' (greater then).
CHEMIX School example - Balancing chemical reactions :
Al + HCl > AlCl3 + H2
