Iron is one of the commonest elements found within the Earth. You probably know the element oxygen. It is the element that we b___in all the time. And elements can combine (结合) to make new things l___H2O. This is hydrogen and oxygen put together, also known as w___! Learning ...
Step-by-Step Solution:1. Understanding the Components: - Plants require three essential elements: carbon (C), hydrogen (H), and oxygen (O). 2. Source of Carbon: - The primary sourc
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). ...
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...
This technology facilitates efficient electrolysis, the process of splitting water molecules into hydrogen and oxygen. The question asks for the factor that improves the efficiency of hydrogen extraction from the ocean. - Option A is partially correct, as solar power can provide energy for the ...

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 renewable...
If1,000dots can represent the air , then776of them are nitrogen ,210 are oxygen ,11 are argon . There are a lot of other gases in the air . Water vapor (水蒸气)and hydrogen (氢)are two examples , but there are only very very small amounts of them . (1) What is air ?A...
dioxide formed the thick atmosphere of present-day Venus.Over time, the rising temperatures would have leveled off, solar ultraviolet radiation having broken down atmospheric water vapor molecules into hydrogen and oxygen.With all the water vapor gone, the greenhouse effect would no longer have ...
hydrogen, and oxygen developed life early in Earth’s history and have radically modified its surface, blanketing huge parts of the continents with greenery.[/highlight12] Life thrives on this planet, and it helped create the planet’s oxygen and nitrogen-rich atmosphere and moderate temperatures...
