Chapter 14Chemical Reactions

SWBAT: Identify and complete combination, decomposition, single replacement, double replacement and combustion reactions

Types of reactions

•There are several general types of reactions, the ones you need to be familiar with are:– Combination– Decomposition– Single Replacement– Double Replacement– Combustion

Combination Reaction

• 2 or more reactants form one product

Decomposition Reaction

•One reactant yields 2 or more products

H2CO3 → H2O + CO2

Cu(s) + 2AgNO3(aq) --> Cu(NO3)2(aq) + 2Ag(s) 2Na(s) + 2H2O(l) --> 2NaOH(Aq) + H2(g)

Single Replacement Reaction

AgNO3 + NaCl → AgCl + NaNO3

Double Replacement Reaction

Combustion Reaction

Organic molecule reacting with oxygen to produce carbon dioxide, water and heat

What type of Reaction?

1. C10H8 + 12 O2  10 CO2 + 4 H2O2. 2 H2O 2 H2 + O2 3. Pb(NO3)2 + 2 KI PbI2 + 2 KNO3 4. Mg + 2 H2O Mg(OH)2 + H2 5. 8 Fe + S8  8 FeS
