没有流行的大象牙膏反应,没有放热反应列表是完整的。这种化学反应的热量伴随着泡沫的喷泉。演示的经典形式使用过氧化氢溶液,碘化钾和洗涤剂。还有一种儿童友好型的反应,使用酵母和家用过氧化物,足够安全,可以让年轻人触摸。铝热反应很像用醋生锈钢丝,除了金属的氧化发生得更加剧烈。尝试铝热反应是你想要燃烧金属和大量的热量。如果你相信“变大或回家”,那么试着在干冰块内进行铝热反应。这放大了过程,甚至可能产生爆炸。如果燃烧的金属是你的一杯茶,只要将任何碱金属滴入水中就不会出错(除非你添加太多)。锂,钠,钾,铷和铯都在水中反应。当您在元素周期表中向下移动时,反应的能量会增加。锂和钠使用起来相当安全。如果您尝试使用含钾的项目,请务必小心。最好将铷或铯在水中的放热反应留给想要在YouTube上出名的人。如果那就是你,给我一个链接,我会展示你冒险的行为。

新加坡南洋理工大学化学Assignment代写:放热反应实例尝试的示范

No list of exothermic reactions would be complete without the popular elephant toothpaste reaction. The heat of this chemical reaction is accompanied by a fountain of foam. The classic form of the demonstration uses a hydrogen peroxide solution, potassium iodide, and detergent. There is also a kid-friendly version of the reaction that uses yeast and household peroxide and is safe enough for young hands to touch. The thermite reaction is much like rusting steel wool with vinegar, except the oxidation of metal occurs much more vigorously. Try the thermite reaction is you want burning metal and a lot of heat. If you believe “go big or go home”, then try performing the thermite reaction inside a block of dry ice. This amplifies the process and may even produce an explosion. If burning metals is your cup of tea, you can’t go wrong with simply dropping any alkali metal in water (unless you add too much). Lithium, sodium, potassium, rubidium, and cesium all react in water. As you move down the group in the periodic table, the energy of the reaction increases. Lithium and sodium are fairly safe to work with. Use caution if you try the project with potassium. It’s probably best to leave the exothermic reaction of rubidium or cesium in water to people who want to get famous on YouTube. If that’s you, send me a link and I’ll show off your risky behavior.
