Single Replacement Reactions and Activity Series

Front

What is a single replacement reaction?

Back

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

Front

What is the activity series of metals?

Back

The activity series is a list of metals arranged in order of decreasing reactivity, used to predict the outcomes of single replacement reactions.

Front

Which metal is more reactive: potassium or calcium?

Back

Potassium is more reactive than calcium.

Front

What happens in a single replacement reaction if the free element is less reactive than the element in the compound?

Back

No reaction will occur.

Front

Predict the product of the reaction: Zn + CuSO4 → ?

Back

ZnSO4 + Cu.

Front

What is the general form of a single replacement reaction?

Back

A + BC → AC + B, where A is a free element and BC is a compound.

Front

What determines whether a single replacement reaction will occur?

Back

The reactivity of the free element compared to the element in the compound, as indicated by the activity series.

Front

In the reaction Li + NaF → ?, what will happen?

Back

Li will replace Na, resulting in the formation of LiF and Na.

Front

What is the result of the reaction: Sn + Cr2(CO3)7 → ?

Back

No reaction occurs because Sn is less reactive than Cr.

Front

Which metal will react with nickel (III) nitrate: cobalt, copper, or tin?

Back

Cobalt will react because it is more reactive than nickel.
