Chemistry Topic 2 Single Replacement HW

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 in chemistry?

Back

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

Front

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

Back

If the free element is more reactive than the element in the compound, the reaction will occur; otherwise, it will not.

Front

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

Back

Yes, the reaction occurs because strontium is more reactive than hydrogen.

Front

What is the result of the reaction: Zn + AuCl2?

Back

The result is ZnCl2 + Au, as zinc replaces gold due to its higher reactivity.

Front

Will the reaction Au (s) + HCl (aq) occur?

Back

No, the reaction will not occur because gold is less reactive than hydrogen.

Front

Which metal is more reactive than calcium?

Back

Potassium is more reactive than calcium.

Front

What will happen in the reaction: Li + NaF?

Back

Lithium will replace sodium, resulting in LiF and Na.

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 is an example of a metal that does not react with acids?

Back

Gold does not react with acids like hydrochloric acid.
