Single Replacement and Activity Series

Front

What is a single replacement reaction?

Back

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

Front

What is the activity series?

Back

A list of metals arranged in order of decreasing reactivity, used to predict if a single replacement reaction will occur.

Front

What determines if a reaction will occur in a single replacement reaction?

Back

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

Front

What happens when a more reactive metal is added to a compound of a less reactive metal?

Back

The more reactive metal will replace the less reactive metal in the compound.

Front

What is the result of the reaction between gold (Au) and hydrochloric acid (HCl)?

Back

No reaction occurs because gold is less reactive than hydrogen.

Front

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

Back

MgCl2 + H2.

Front

What is the outcome of the reaction: LiBr + Na?

Back

No reaction occurs because sodium cannot replace lithium.

Front

What is the significance of solubility rules in chemical reactions?

Back

They help predict whether a reaction will occur based on the solubility of the products.

Front

What is an example of a single replacement reaction?

Back

Zn + CuSO4 → ZnSO4 + Cu.

Front

What does it mean if a reaction is classified as 'no reaction'?

Back

It means that the reactants do not produce any products due to the reactivity of the elements.
