What is a single replacement reaction?

Back

A single replacement reaction is a type of chemical reaction where one element replaces another in a compound. Example: Zn + 2HCl → H₂ + ZnCl₂.

What is a double replacement reaction?

Back

A double replacement reaction is a type of chemical reaction where two compounds exchange ions or bonds to form two new compounds. Example: AgNO₃ + NaCl → AgCl + NaNO₃.

What is the general formula for a decomposition reaction?

Back

AB → A + B, where AB is a compound that breaks down into its components A and B.

What is the general formula for a single replacement reaction?

Back

A + BC → AC + B, where A replaces B in the compound BC.
