Types of Chemical Reactions
This is not an exhaustive list of reactions, but for this chapter, we will focus on the following reactions
• Synthesis (combination)• Decomposition• Single replacement• Double replacement• Combustion
• Quiz Time
Click on each of the following reactions to review its concepts
Combustion
• Occurs when a compound reacts with atmospheric oxygen
• CxHy + O2 → CO2 + H2O
• CH4 + O2 → CO2 + H2O
Synthesis
• Taking single elements or compounds and combining them into one compound
• A + B → AB
• 2 Na + H2 → 2NaH
• Ca + F2 → CaF2
Decomposition
• A compound breaking into several compounds or elements
• AB → A + B
• H2O2 → H2O + H2
Single replacement• Occurs when a single element and a
compound react to form a single element and a compound
• A + CD → C + AD (cationic single replacement)
• Li + CuNO3 → Cu + LiNO3
• B + AD → D + AB (anionic single replacement)
• F2 + BaI2 → I2 + BaF2
Double Replacement• Occurs when two compounds react
with each other and form two new compounds
• AB + CD → CB + AD
• NaOH + HCl → NaCl + H2O
• 2LiBr + MgSO4 → Li2SO4 + MgBr2
