(6 cards)
1
Q

A
Two simple molecules to make a larger or more complex product
A + B = AB
2
Q
What is single displacement
A
One element replaces or displaces an element in a compound
When involving ionic and metal, the cation is the one replaces in the compound
Polyatomic ions are a single unit
A + BC = AC + B
3
Q
What is double displacement
A
When two elements in different compounds trade places
Do not swap metal for non-metal
Treat polyatomic ions as one unit
AB + CD = AD + CB
4
Q
What is a precipitate
A
A solid formed from the reactions of two solutions
5
Q
