Today’s Agenda
Today’s Objectives
Scholars will differentiate between single-displacement, double-displacement, and combustion reactions.
Single/Double Replacement and Combustion Reactions
Chemical Reactions
There are 5 types of chemical relationships(reactions) at the prom this year.
1. Combustion2. Synthesis3. Decomposition4. Single-Displacement5. Double-Displacement
Drama on the Dance Floor!
A SINGLE-DISPLACEMENT REACTION is one in which a single element replaces a similar element in a compound
A + BX AX + B A couple is dancing, and someone else cuts in
Single-Displacement in Action
Single-Displacement Example: Zn + CuCl2
ZnClCl Cu +
A + BX AX + B
ClCl Zn Cu+
Swing Fever!
A DOUBLE-DISPLACEMENT REACTION is one in which ions switch places.
AX + BY AY + BX Two couples are dancing and decide to switch
partners!
Double-Displacement in Action
Double-Displacement Example: MgO + CaS
AX + BY AY + BX
SOMg Ca
+O S
Mg Ca+
Today’s Agenda
It’s getting hot in here…
A COMBUSTION REACTION is one in which a hydrocarbon burns in the presence of oxygen gas, releasing CO2 and H2O
A hydrocarbon is any compound made of hydrogen and carbonEx: CH4, C2H4
Combustion ExamplesPredict products of the reactions!
1. CH4(g) + O2(g)
2. C2H2(g) + O2(g)
CO2(g) + H2O(g)
CO2(g) + H2O(g)
