Hydrogen is the simplest, cleanest and most abundant element in the universe. Fuel cells generate electricity through an electro-chemical process that combines hydrogen and oxygen to produce pure water as a by-product. Winning technology Organisations who operate in off-grid environments are looking ...
O2 C6H12O6 Fish and aquatic animals cannot split oxygen from water (H2O) or other oxygen-containing compounds. Only green plants and some bacteria can do that through photosynthesis and similar processes. Virtually all the oxygen we breath is manufactured by green plants. A total of three-fourths...
Hydrogen can also be produced through electrolysis. This is when electricity is used to split water (H2O) into hydrogen (H2) and oxygen (O2). If the electricity used in this process is generated with renewable sources, the production process is free of emissions. This type of hy...
The size of oxygen atom is quite small. The oxygen atoms can be linked to each other by double bond (O=O) because p pi-p pi bonding is possible in this case. Therefore, oxygen exists in the gaseous state as discrete molecules. Multiple bonding is not so
For the polyatomic ion OH−, oxygen is listed first instead of hydrogen. However, in the name, it is reversed as hydroxide. Why? Chemical Formula: The chemical formula gives us the description of a molecule: Ït sets the nature and nu...
Vinegar is a bacteria ferment.Produces a MOV Mother of Vinegar very similar to a SCOBY. For every mole of sugar the yeast expels one mole of CO2 (Carbonation) and one mole of alcohol. The yeast are also using O2 (oxygen) . O2, CO2, and alcohol are all lighter than water and ...
Although molecular oxygen (O2) does not participate directly in any of the reactions of the citric acid cycle, the cycle operates only when O2 is present. Explain this observation. Explain the Krebs Cycle. Explain Krebs cycle in ...
