A reaction in which a more reactive element takes the place of a less reactive element in one of its compounds or in solution Define oxidation in the context of loss and gain of electrons Oxidation is the loss of electrons Define reduction in the context of loss and gain of electro...
Energy changes Exothermic reactions Examples: respiration, combustion, oxidation, neutralisation Energy ‘exits’ reaction – heats surroundings Thermometer readings rises Uses: self heating can and hand warmers Energy changes Endothermic reaction Examples: photosynthesis, thermal decomposition, reaction of citric...
Reaction of metals with water Week 7 – Other Chemical Reactions Metal carbonates such as calcium carbonate break down when heated strongly. This is called thermal decomposition. Here are the equations for the thermal decomposition of calcium carbonate: Other metal carbonates decompose in the same way...
