Single Replacement Reactions 1.) There are 5 major types of chemical reactions – A. Combustion: burns, explodes – B. Synthesis: to make something new – C. Decomposition: break down – D. Double Replacement: 2 elements change – E. Single Replacement: 1 element changes
2
Single Replacement Reactions 2.) In a single replacement reaction, 1 element replaces another element in a compound.
3
Replacement Reactions 3.) Not all metals can be replaced, we use the reactivity series of metals list to predict changes. 4.) The higher an element is on the list, the more likely it is to replace another element.

Replacement Reactions
5
Single Replacement Reactions Example 1 : Zn + Ag(NO 3 ) Zn (No 3 ) + Ag - Zinc is higher on the list than Silver, therefore it can switch places.
6
Single Replacement Reactions Example 2 : Au + Ni(SO 4 ) No reaction - Gold is NOT higher on the list than Nickel, therefore it cannot switch places.
7
Single Replacement Reactions Example 3: Zn + NiCl 2 ZnCl 2 + Ni Why was Zn able to switch places with Ni?
8
Single Replacement Reactions Example 4: Fe + MgCl 2 No reaction Why did the reaction not occur?
