Introduction to Chemical Reactions

For each of the reactions performed, — predict the reaction type (combination, decomposition,

combustion, single or double displacement)

— record your observations : Your observation includes color and physical state.    Physical state:   solid (s)  or precipitate (ppt)  : a solid  insoluble in water,      g : gas        and l : liquid

 

— write the balanced “molecular” equation, including all physical              states.
