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
The reaction between hydrogen and oxygen produces water. What is the correct balanced equation? A. H₂ + O₂ = H₂O B. 2H₂ + O₂ = 2H₂O C. H₂ + 2O₂ = 2H₂O D. 2H₂ + 2O₂ = 4H₂O 相关知识点: ...
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...
hydrogen (H2) and oxygen (O2) using electricity. This process, called water electrolysis, is a promising option for carbon-free hydrogen production since the electricity can be sourced from nuclear or renewable energy, such as wind and solar. Scientists and engineers are working to improve and ...

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...
What happens when calcium carbonate is heated? A. It forms hydrogen gas and oxygen gas. B. It combines with another substance to form a new compound. C. It decomposes into calcium oxide and carbon dioxide. D. It undergoes a single replacement reaction. ...
Hydrogen molecules violently react with oxygen when the existing molecular bonds break and new bonds are formed between oxygen and hydrogen atoms. As the products of the reaction are at a lower energy level than the reactants, the result is an explosive
