TRANSCRIPT
SynthesisSynthesis
2 or more elements or compounds combine to make one product
A + B ABElement + element yields compound
One compound is broken down into 2 or more elements or compounds
AB A + B
Decomposition
Compound yields element + element
Single Replacement
Replacing of one element in a compound with another element
AB + C AC + BCompound + element yields compound + element
Double Replacement
Two compounds exchange elements
AB + CD AD + CB
Compound + compound yields compound + compound
Combustion
Fuel burns in the presence of oxygen to produce carbon dioxide and water (along with other by-products)
ALWAYS EXOTHERMIC
Fuel + O2 CO2 + H2O
burning
Examples:
S - 2Mg + O2 2MgO
D - 2H2O 2H2 + O2
SR - 2Al + 3CuCl2 2AlCl3 + 3Cu
DR - FeCl2 + Na2CO3 2NaCl + FeCO3
Identify the type of reaction:
4Al + 3O2 2Al2O3
Mg + 2HCl H2 + MgCl2
Pb(NO3)2 + K2CrO4 PbCrO4 + KNO3
2HgO 2Hg + O2
Fe + CuCl2 FeCl2 + Cu
3H2 + N2 2NH3
4C3H5(NO3)3 12CO2 + 6N2 + 10H2O + O2
