Organize the given reactants into single replacement and other reactions.

Single Replacement Reactions

Other

• But not all single replacement reactions occur.

• Remember, 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).

​

• Notice the placement of magnesium in comparison to zinc.

• Since magnesium is higher on the Activity Series than zinc, a reaction will occur.

• Magnesium replaces zinc in the compound.

​

• It is important to remember when you are writing the chemical formulas for the predicted products that...

  ALL COMPOUNDS ARE NEUTRAL!

​

Multiple Choice

Predict the products for the given reaction:

Ca(s) + K₂SO₄(aq) →

• CaSO₄ + K

• CaK + SO₄

• Ca₂SO₄ + K

• no reaction

• Notice the placement of calcium in comparison to potassium.

• Since potassium is higher on the Activity Series than calcium, a reaction will NOT occur.

• Calcium cannot replace potassium in the compound.

​

• 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.

Multiple Choice

Predict the products for the given reaction:

Cl₂(g) + NaI(s) →

• NaCl₂ + I

• NaCl + I₂

• ICl + Na

• no reaction

Multiple Choice

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.

Multiple Choice

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.
