A + X = AX

Answer 1

Synthesis/Combination

Question 2

One substance reacts to form two or more substances

Answer 2

Decomposition

Question 3

A metal replaces a metal ion (or H+) in a cmpd
A + BX = AX + B
A nonmetal replaces a nonmetal ion in a cmpd
Y + BX = BY + X

Answer 3

Single Displacement

Question 4

Ions of two compounds exchange places with each other
AX + BY = AY + BX

Answer 4

Double Displacement
