GradeBuddy is best used as a supplement to your own notes, not as a substitute.Current LectureElements in Redox Reactions (atom/element in one side and compound on the other)TYPES:1. Combinationa. X+YZ b. Where either X or Y or both is an element. One ALWAYS has to be an element.2. Decompositiona. ZX+Yb. Where X or Y or both are elements. Again, one HAS to be an element.3. Displacement (single)a. There is double displacement. These are the precipitation and acid base reactions we did where the partners were “swapped”. This is NOT a redox reaction… (AB+CDAD+CB)b. Single displacement IS a redox reaction. An atom of one element displaces the ion of another. It is common in metals.i. X+YZXZ+Yc. Activity Series in Metalsi. Metals are ranked by their ability as reducing agents.ii. Any metal can reduce a metal lower on the list. iii. LIST IS FIGURE 4.24 IN TEXTBOOKiv. Example: Zinc cannot displace copper but copper can displace zinc4. Combustion a. Combines with oxygenb. Usually producing heat and/or lightc. Most common is fuel burning with O2 gas to produce CO2(g) and H2O(g)Reversibility of Reactions“Equilibrium state”Will cover this EXTENSIVELY in Chem 1062.There is NO net reactionCommon in weak acids and bases which dissociate slightly.For Chem 1061 only worry about FORWARD
