How can metals be placed in order of their reactivity? Add the metals to water or acid and see which ones react the most (by how much fizzing there is) What is the name for a reaction where oxygen is removed from a compound? Reduction Explain why zinc can be extracted from zinc...
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...
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. Here are the equations for...
