5 Common Reaction Types:-synthesis -decomposition-combustion -single displacement-double displacementsynthesis - means to make something or buildExample: synthetic material, photosynthesis
decomposition- means to something downstarts out as 1 whole and breaks into 2 or more
EX: decomposing (dead) animals or garbage
5 Common Reaction Types:-synthesis -decomposition-combustion -single displacement-double displacementCombustion-burningalways has CO2 as a product
actual example:
5 Common Reaction Types:-synthesis -decomposition-combustion -single displacement-double displacementsingle displacment- 1 “switch”one element switches or hops to another partner
Cl switches to pair w/ Ca in the product
Like a divorce and a remarriage
5 Common Reaction Types:-synthesis -decomposition-combustion -single displacement-double displacementdouble displacment- 2 “switch”2 elements switch or change partners
Na & So4 both switches partners in the product
5 Types of Chemical 5 Types of Chemical ReactionsReactionsGuess which common reaction
type:
synthesis
4Fe + 3O2 Fe2O3
2 substances
1 product
Examples of synthesis reactions:
A skinny bird (reactant) and the worm (reactant) combine to make one product…..one fat bird.

rain water & carbon dioxide in the air
combine to form
carbonic acid
carbon monoxide gas & oxygen gas
combine to form

Guess which common reaction type?
reactant -------> product + product
decomposition
1) water can be broken down into
hydrogen gas & oxygen gas
2)To visualize this reaction look at the cartoon:
the egg (the reactant), which contained the turtle at one time, now has opened and the turtle (product) and egg shell (product) are now two separate substances.

Ex: mercury oxide decomposes into mercury and oxygen
2HgO 2Hg + O2

type?
Single Displacement
Zn + 2HCL ZnCl2 + H2
The chemical equation for this single replacement reaction looks like:
reactant + reactant -----> product + product
5 Types of Chemical 5 Types of Chemical ReactionsReactionsSingle Replacement Reaction Cont’d:
Zn + 2HCL ZnCl2 + H2
To visualize this reaction look at the cartoon:
the guy in the orange shirt steals the date of the other guy.
So, a part of one of the reactants trades places and is in a different place among the products
5 Types of Chemical 5 Types of Chemical ReactionsReactionsGuess which common reaction
type?
double displacement
AgNo3 + NaCl AgCl + NaNo3
5 Types of Chemical 5 Types of Chemical ReactionsReactions
parts of two compounds switch places to form two new compounds
Two reactants yield two products.
4) Double Displacement (Replacement) Reaction:•a reaction in which the elements in
two compounds are exchanged
AX + BY AY + BXthey switch partners
reactant + reactant -----> product + product
The chemical equation for double replacement reaction looks like:
EX: silver nitrate combines with sodium
two new compounds--silver chloride & sodium nitrate are formed
because the sodium and silver switched placesWHY?…
