combustion
synthesis
decomposition
single replacement
double replacement
1 reactant breaks apart into 2 or more smaller products
decomposition
2 or more reactants combine to make 1 product
synthesis
O2 as a reactant & CO2 and water as products
combustion
1 element & 1 compound in products & reactants
single replacement
2 compounds in reactants & products
double replacement
(a) reactions have 1 compound on both sides while (b) reactions have 2 compounds on both sides. (c) reactions break apart. (d) reactions combine. (e) reactions must have O2 as a reactant & CO2 and H2O as products.
The reactants will be bigger than the products in a (a) reaction. (b) reactions have 1 element and 1 compound. The products will be bigger than the reactants in a (c) reaction. Fuel and oxygen are needed in a (d) reaction. (e) reactions have 2 compounds.
Put the equations in this order: decomposition, synthesis, combustion, single replacement, double replacement.
The (a) are on the right side of the arrow and the (b) are on the left side of the arrow.
