Predicting Products of Chemical Reactions: Single Displacement

Single replacement reactions replace one element from a compound with another element.

–A compound and an element react, and the element switches places with part of the original compound.

  • A + BC –> B + AC where A is a metal, or
  • A + BC –> C + BA where A is a non-metal
