Explain how to determine if a reaction will or will not occur during single replacement.
6. Complete and balance each of the following chemical equations that describe single displacement/replacement reactions. If no reaction is expected to occur, then explain why. You will need to refer to the activity series table (Table 8.2) of the Hein text. Optional (as directed by instructor): Indicate the compound "Type" that best describes each reactant and product from the following: metal, non-metal, metal oxide, non-metal oxide, oxy- acid, acid, metal hydroxide, halogen, metal chloride, metal halide, metal sulfate, metal nitrate, metal phosphate, metal carbonate, metal bicarbonate, metal chlorate, salt or other. a b. e d. c. a Al(s) + b.
