It is composed of what sounds like a bizarre mixture: fly-ash, a fine-grained waste product from coal-fired power stations; carbon nanotubes, cylindrical molecules made of elemental carbon; and two binding agents, sodium silicate and sodium hydroxide.
煤灰,火力发电厂排放细颗粒废弃物;碳纳米管,即柱状碳分子;还有两种黏合剂:硅酸和氢。
Remember that we can look up the standard enthalpy of formation for all the products and reactants in the back of a textbook or online, the chemical reaction between hydrochloric acid and sodium hydroxide produces liquid water and sodium chloride.
请记住, 们可以在教科书后面或网上查找所有产品和反应物标准生成焓,盐酸和氢之间学反应生成液态水和氯。
