Synthesis
2 or more elements or simple compounds joined together to create one new compound
A + B = AB
Mg + O2 =
2Mg + O2 = 2MgO
Synthesis
Metal plus Nonmetal combine to form an ionic compound
Ca + S =
Ca + S = CaS
Synthesis
M + Nm combine to form an ionic compound
Li2O + H2O =
Li2O + H2O = 2LiOH
Synthesis
Metallic oxide combines with water to give a metallic hydroxide
CO2 + H2O =
CO2 + H2O = H2CO3
Synthesis
Non Metallic Oxide Combines with water to produce an acid
Decomposition
One substance broken down into two or more similar substances
AB = A+B
Ag2O =
2Ag2O = 4Ag + O2
Decomposition
Simple ionic compounds containing 2 elements decompose into their 2 elements
NiCO3 =
NICO3 = NiO + CO2
Decomposition
When a metallic carbonate is heated CO2 and metallic gas is formed
NaClO3 =
NaCl + O2
Decomposition
When metallic chlorate is heated it decomposes to form a metallic chloride and O2
NaOH =
2NaOH = Na2O + H2O
Decomposition
When some metallic hydroxides are heated they decompose to form metal oxide and water
H2SO3 =
H2SO3 = SO2 + H20
Decomposition
Some acids decompose to form a nonmetal oxide and water
Single Replacement
Replace one ion in a compound with another ion that matches signage
AB + C = CB + A
Au + KNO3 =
No reaction
Au can not switch with K
Active metal list
Top to bottom
Li, K, Ba, Ca, Na, Mg, Al, Zn, Fe, Ni, Sn, Pb, H, Cu, Hg, Ag, Au
Zn + AgNO3 =
Zn + 2AgNO3 = 2Ag + Zn(NO3)2
Single replacement
Zinc is higher than Ag
Na + H2O =
2Na + 2H2O = 2NaOH + H2
Single replacement
Group 1 and 2 metals when added to water produce a metallic hydroxide (OH) and H2 gas
Double Replacement
Ionic compounds switch cationsnso the anions have a new partner
NaOH + CaBr2 =
2NaOH + CaBr2 = 2NaBr + Ca(OH) 2
Double replacement
HBr + KOH =
HBr + KOH = KBr + HOH
double replacement
Naturalization
Acid + base yield water and a salt
Combustion
Fuel source combined with oxygen produces heat, CO2, and water vapor
C4H10 + O2 =
2C4H10 + 13O2 = 10H20 + 8CO2
Combustion
Diatomic Elements
H, N, O, F, Cl, Br, At
