Pre AP - Day 6 - Activity Series Review

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 metal will displace another in a chemical reaction.

Front

How can you determine if a reaction will occur based on the activity series?

Back

If a more reactive metal is present than the metal in the compound, the reaction will occur. If the metal is less reactive, no reaction will take place.

Front

What happens when a more reactive metal reacts with a less reactive metal compound?

Back

The more reactive metal will displace the less reactive metal from its compound.

Front

What is an example of a reaction that occurs based on the activity series?

Back

Ca + Pb(NO3)2 → Ca(NO3)2 + Pb; Calcium displaces lead because it is more reactive.

Front

What is an example of a reaction that does not occur based on the activity series?

Back

Ag + LiBr → No reaction; Silver cannot displace lithium because it is less reactive.

Front

What does it mean if no reaction occurs in a displacement reaction?

Back

It means that the metal attempting to displace another is less reactive than the metal in the compound.

Front

What is the significance of the position of metals in the activity series?

Back

The position indicates their reactivity; metals higher in the series are more reactive than those lower down.

Front

What is the outcome of the reaction Br2 + NaF based on the activity series?

Back

No reaction will occur because bromine cannot displace fluorine.

Front

What will happen in the reaction Li + NaF?

Back

Li will replace Na because lithium is more reactive than sodium.

Front

What is the general rule for single displacement reactions?

Back

A more reactive element can displace a less reactive element from a compound.
