What is a Chemical Reaction?

A process in which atoms of the same or different elements rearrange themselves to form a new substance. While they do so, they either absorb heat or give it off.

Double Replacement Reactions

CaCl2 + 2 NaHCO3 ----> 2 NaCl + CaCO3 + H2O+ CO2.
Double Displacement Reaction
K2CrO4 + 2AgNO3 = Ag2CrO4 + 2KNO3
Double Replacement Reactions

Single Chemical Reactions

2HCl+Zn ---> ZnCl2 + H2
HCl + Zn = ZnCl2 + H2
