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. Combustion 2. Synthesis 3. Decomposition 4. Single-Displacement 5. 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 + CuCl 2  Zn Cl Cu + A + BX  AX + B Cl 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 S O  Mg Ca + O S Mg Ca +

It’s getting hot in here… A COMBUSTION REACTION is one in which a hydrocarbon burns in the presence of oxygen gas, releasing CO 2 and H 2 O A hydrocarbon is any compound made of hydrogen and carbon  Ex: CH 4, C 2 H 4

Combustion Examples Predict products of the reactions! 1. CH 4 (g) + O 2 (g)  2. C 2 H 2 (g) + O 2 (g)  CO 2 (g) + H 2 O(g)
