Single Replacement and using the Activity Series

Front

What is a single replacement reaction?

Back

A single replacement reaction is a type of chemical reaction where one element replaces another element in a compound.

Front

What is the activity series?

Back

The activity series is a list of metals arranged in order of decreasing reactivity. It helps predict whether a single replacement reaction will occur.

Front

How can you determine if a single replacement reaction will occur?

Back

To determine if a single replacement reaction will occur, compare the reactivity of the free element with the element in the compound using the activity series.

Front

What are the products of the reaction: Mg + CuSO₄ → ?

Back

The products are Cu + MgSO₄.

Front

What is the predicted outcome of the reaction: Br₂ + KF?

Back

No reaction occurs because Br₂ is less reactive than K.

Front

What happens when Cu is added to HCl?

Back

No reaction occurs because Cu is less reactive than hydrogen.

Front

What are the products of the reaction: Mg + HCl?

Back

The products are MgCl₂ + H₂.

Front

Why does no reaction occur when LiBr is mixed with Na?

Back

No reaction occurs because Na is not higher than Li in the activity series.

Front

What is the general form of a single replacement reaction?

Back

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

Front

What role does the activity series play in predicting reactions?

Back

The activity series helps predict whether a more reactive element can displace a less reactive element from a compound.
