Exam III notes: 4.7 Oxidation/reduction reactions = REDOX reactions Oxidation means losing electrons, reduction means gaining electrons Oxidation can also refer to the gain of oxygen atoms and/or the loss of hydrogen atoms. Reduction can also refer to the loss of oxygen atoms and/or the gain of hydrogen atoms The oxidizing agent is the molecule that accepts the electrons and the reducing agent is the molecule that gives them away There are 5 types of redox reactions: 1) combustion 2) respiration 3) rusting 4) bleaching (common bleaches are oxidizing agents) 5) batteries 4.8 the heat given off or gained in a reaction is called the heat of reaction A reaction that gives off heat is exothermic A reaction that absorbs or requires heat for the reaction to continue is endothermic Heat given off in a combustion reaction is aptly called the heat of combustion 5.2 pressure is the force per unit area exerted against a surface Atmospheric pressure can be measured using a barometer Pressure is mostly commonly measured in mm Hg, but also in torr, or atm
