Single Replacement Reactions

Front

What is a single replacement reaction?

Back

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

Front

What is the general form of a single replacement reaction?

Back

A + BC → AC + B

Front

What determines if a single replacement reaction will occur?

Back

The activity series of metals; a more reactive metal can replace a less reactive metal.

Front

What is the activity series of metals?

Back

A list of metals arranged in order of decreasing reactivity.

Front

What happens when potassium (K) reacts with water (H2O)?

Back

K + H2O → KOH + H2 (Potassium hydroxide and hydrogen gas are produced).

Front

What is the result of zinc (Zn) reacting with gold chloride (AuCl2)?

Back

Zn + AuCl2 → ZnCl2 + Au (Zinc replaces gold in the compound).

Front

What products are formed when bromine (Br2) reacts with potassium iodide (KI)?

Back

Br2 + KI → KBr + I2 (Bromine replaces iodine).

Front

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

Back

Cobalt will react because it is more reactive than nickel.

Front

What is the result of lithium bromide (LiBr) reacting with sodium (Na)?

Back

No reaction will occur because sodium cannot replace lithium in the compound.

Front

What is a common characteristic of single replacement reactions?

Back

They often involve the transfer of electrons and the formation of new compounds.
