Types of Equations
1.decomposition- break down
2.synthesis- putting together
3.single replacement
4.double replacement
5.compustion
Combustion of hydrocarbons
3 types:
Complete Combustion- CO
2
+H
2
O
Incomplete Combustion-CO+H
2
O
Limited Combustion-C+H
2
O
Types of Decomposition Reactions
1.Metallic carbonates
2.metallic chlorates
3.weak acids
4.weak hydroxides (bases)
5.binary compounds (electrolysis)
6.hydrates
7.carbohydrates
Metallic Cabonates
metallic carbonates-> metallic oxide + CO
2
ex. MgCO
3
-> MgO+ CO
2
Metallic Chlorates
Metallic Chlorates-> metallic chloride+ O
2
ex.2KClO
3
-> 2KCl + 3O
2
Weak Acids
Weak acid-> non metalic oxide + H
2
O
ex.2H
3
PO
4
->P
2
O
5
+ 3H
2
O
Weak Hydroxides
weak hydroxides-> metal +H
2
O
ex.Mg(OH)
2
->MgO + H
2
O
Binary Compounds
Binary Compound-> metal + nonmetal
ex. 2KCl-> 2K + Cl
2
Hydrates
hydrates->salt x #H
2
O
ex. MgSO
4
X 7H
2
O -> MgSO
4
+ 7H
2
O
Carbohydrates
carbohydrates-> C + H
2
O
ex. C
12
H
22
O
11
-> 12C + 11H
2
O
Synthesis (composition)
switch products w/ reacts from decomp.
ex. Na
2
O + H
2
O-> sodium hydroxide (NaOH)
ex.SO
2
+H
2
O-> H
2
SO
3
Single Replacement
element+ compound-> element+ compound
if metal is higher up in the group on the periodic table it will be able to replace the one in the compound
Double Replacement
compound+compound-> compound + compound
LOOK OVER STOICHIOMETRY!
ALL DONE =)
GOOD LUCK!!!
