Organize the given reactants into single replacement and other reactions.

Single Replacement Reactions

Other

• But not all single replacement reactions occur.

• We use an activity series to determine of a single replacement reaction will occur.

  • One for metals (which includes hydrogen).

  • One for nonmetals (which is basically the halides on the periodic table).

• Watch the video to see how it works.

​

Multiple Choice

Let's try again. Do you understand how the activity series works?

A piece of magnesium ribbon is placed in a beaker containing an aqueous solution of copper(II) sulfate. Will a reaction take place?

• A reaction will take place, because the copper(II) sulfate is an aqueous solution.

• A reaction will take place because magnesium is more reactive than copper.

• A reaction will NOT take place because magnesium is less reactive than copper.

• A reaction will NOT occur because the aqueous solution needs to be heated.

Multiple Choice

Let's take a moment and see if you understood what the video has shown so far.

A solid piece of copper is placed into a beaker containing hydrochloric acid. Will a reaction take place?

• A reaction will take place, because everything reacts with acids.

• A reaction will take place because copper is more reactive than hydrogen.

• A reaction will NOT take place because copper is less reactive than hydrogen.

• A reaction will NOT occur because copper is much stronger than acids.

Place the reactions in place based on whether they will react or not.

Reaction will occur.

No Reaction

• Although we have primarily been looking at metals replacing metals, single replacement reactions also occur between nonmetals.

• The nonmetal reactions you will be responsible will mostly deal with the halogens.

• Look at the periodic table and determine how to use it as an activity series for the nonmetals.
