Synthesis ReactionsSynthesis Reactions
Two substances react to form a single product.
X + Y XY
Simple compounds make more complex ones.
Decomposition Decomposition ReactionsReactions
A single reactant decomposes or breaks down into two or more products.
A B + C(decomposition of a metal chlorate or metal carbonate are the most common)
More complex compounds make less
complex ones.
Combustion ReactionsCombustion Reactions
One reactant (fuel) combines with oxygen to produce an oxide and water.
Fuel + O2 oxide + H2O
The substance reacts with O2 in an exothermic
reaction.
Two Types of Two Types of Combustion ReactionsCombustion Reactions
Incomplete combustion:CxHy + 02 CO + H20
Complete Combustion:CxHy + O2 CO2 + H2O
Single Replacement Single Replacement ReactionsReactions
One, more reactive element, replaces another.
M + AX MX + A
One atom takes the place of another.
Two Types of Single Two Types of Single Replacement ReactionsReplacement Reactions
Single Replacement of a Halogen:Z2 + AX AZ + X2
Single Replacement of a Metal:M + AX MX + A
HINT: LOOK AT 1ST REACTANT!!
Double Replacement Double Replacement ReactionsReactions
A reaction in which the cations and anions of both reactants switch partners.
AX + DZ AZ + DX
Two atoms trade places.
Activity SeriesActivity Series
A list of elements in order of their chemical reactivity and are useful I predicting whether a chemical reaction will occur.– For metals- greater activity means an
ability to lose electrons easily.– For non-metals- greater activity means
an ability to gain electrons easily.
Activity of MetalsActivity of Metals Using the activity series shown
in Table 8-3, predict whether each of the possible reactions listed below will occur.
a. Cr(s) + H20(l)
b. Pt(s) + 02(g)c. Cd(s) + 2HBrd. Mg(s) + steam
