Single+Replacement

flat =Description= __**Description of Suspect and Behavior (Description of Reaction & General Equation)**__ Occurs when an element or an ion moves out of one compound into another. Many take place in water solutions. The amount of energy involved in a single displacement reaction is usually less than involved in a synthesis or decomposition reactions.

=Examples= __**Examples Illustrating the behavior (Equations)**__ Cl2 + NaBr ---> NaCl + Br2 Zn + 2HCl ---> ZnCl2 + H2 Cu + 2AgNO3 ---> 2Ag + Cu(NO3)2 Zn + CuCl2 --> ZnCl2 + Cu Cl2 + NaBr --> NaCl + Br2  Mg + HCl --> MgCl2 + H2  2AgNO3 + Zn → 2Ag + Zn(NO3)2 Zn + CuCl2 ZnCl2 + Cu
 * Fe+CuSO****4 >** **Cu+ FeSO4**

=Real-Life Examples= __**Real-Life examples showing this behavior and documentation (with equations and video/picture)**__ Baking soda (NaHCO3) reacts with acidic substances (HA) in cake batter in a double replacement reaction: NaHCO3 + HA --> Na A + H(HCO3)



__//**Potassium chloride and silver**//__ KCl+Ag ---> AgCl +K The rusting of galvanized steel. Fe2+ + 2 H2O ⇌Fe(OH)2 + 2 H+
