Why is hydrogen important as a future clean energy source? A fuel is a chemical that can be ‘burnt’ to provide useful energy. Burning normally means that chemical bonds between the elements in the fuel are broken and the elements chemically combine with oxygen (often from the air). ...
题目What is the product of the reaction between hydrogen and oxygen? A. Nitrogen B. Carbon dioxide C. Water D. Chlorine 相关知识点: 试题来源: 解析 C。氢气和氧气反应生成水。氮气、二氧化碳和氯气都不是氢气和氧气反应的产物。反馈 收藏
What is renewable hydrogen? Renewable hydrogen is hydrogen derived from water. It’s created using a process called electrolysis, wherein electricity from renewable sources is used to split the hydrogen molecules from the oxygen molecules in water. Because the electricity used here comes from renewabl...
One may of making hydrogen is a process called electrolysis, when electricity is passed through a substance to force a chemical change — in this case, splitting H2O into hydrogen and oxygen. Green hydrogenis when the energy used to power electrolysis comes from renewable sources like wind, wate...
Scientists have created a catalyst they believe can radically reduce the price needed to create hydrogen.
题目What is the main component of ocean water? A. Salt B. Fresh water C. Oxygen D. Hydrogen 相关知识点: 试题来源: 解析 A。海水的主要成分是盐。选项 B 淡水在海水中所占比例很小;选项 C 氧气是海水中的成分之一,但不是主要成分;选项 D 氢是构成水分子的元素之一,但不是海水的主要成分。所以...
In part 1 of a series on hydrogen in Europe, we cover hydrogen basics, its relevance, its various colors, and the impact of decarbonization regulation.
Using hydrogen in power plants can reducecarbon dioxideemissions when either blended or alone inspecialized turbines, or infuel cells, which consume H₂ and oxygen, or O₂, to produce electricity, heat and water. But it's typically not entirely CO₂-free. That's in part because isolatin...
A. Hydrogen Oxygen B. Hydrogen two Oxygen C. Hydrogen dioxide D. Water 相关知识点: 试题来源: 解析 D。H2O 是水的化学式,表示由两个氢原子和一个氧原子组成的水分子。选项 A、B 表述错误,选项 C 是二氧化氢,不是 H2O 的含义。在化学学科中,H2O 是一个重要的缩略词。反馈 收藏 ...
When carbon capture is integrated with the production of hydrogen from natural gas, we call it blue hydrogen. Through a process called electrolysis, however, which involves using renewable electricity to split water molecules into hydrogen and oxygen, it is possible to produce hydrogen in a way ...
