Single Replacement Reactions

Front

What is a single replacement reaction?

Back

A chemical reaction where one element replaces another element in a compound.

Front

What is the activity series?

Back

A list of metals arranged in order of decreasing reactivity, used to predict the outcomes of single replacement reactions.

Front

What are the predicted products of the reaction: Br2 (l) + KI (aq)?

Back

KBr + I2.

Front

In a single replacement reaction, what determines if a reaction will occur?

Back

The reactivity of the elements involved, as indicated by the activity series.

Front

What happens when a less reactive metal is placed in a solution of a more reactive metal salt?

Back

No reaction occurs.

Front

What is the result of the reaction: Au (s) + HCl (aq)?

Back

No Reaction.

Front

Which metal is more reactive: magnesium or silver?

Back

Magnesium is more reactive than silver.

Front

What is the general form of a single replacement reaction?

Back

A + BC → AC + B, where A is a more reactive element replacing B in the compound BC.

Front

What is the outcome of the reaction: K + AgNO3?

Back

Ag + KNO3.

Front

How can you determine the order of reactivity among metals?

Back

By using the activity series to compare their positions.
