Question

There are 5 basic types of chemical reactions:

A) Synthesis - two or more reactants combine into one product (A + B --> AB)
B) Decomposition - one reactant breaks down into two or more products (AB --> A+B)
C) Single Displacement - one element replaces a similar element in a compound (A + BX --> AX + B)
D) Double Displaceemnt - two compounds exchange ions/elements (AX - BY-> AY + BX)
E) Combustion - a substance combines with oxygen to produce carbon dioxide & water ( + 02 --> CO2 + H20)
Identify which type of reaction (from above) each of the following are:
1) CH 2 + O2 --> CO2 + H20
6) Ag + LINO3 --> Li + AgNO3
2) P4 +02 --> P203
7) O2 + CH3OH- H20 + CO2
3) Na3PO4 +KOH --> NaOH + K3PO4
8) (NH4)2CO3 --> NH3 + CO2 + H2O
4) Zn + H2CO3 -> ZnCO3 + H2
9) C + H2 > C3H8
5) CaCO3 -> CaO + CO2
10) C20 + FeBr3 --> Fe2O3 + CsBri
