For the first time, Northwestern University scientists have watched water molecules in real-time as they prepared to give up ...

A fuel cell stack, or bank, serves as the ‘engine,’ where many cells facilitate a simple chemical reaction between oxygen from the air and the pressurized hydrogen fuel stored onboard the vehicle.

energy is used to split water molecules into hydrogen and oxygen. The hydrogen is needed for the second stage of reactions and the oxygen is released by the plant as a waste product. In the ...

Water is essential for life, but when did it first appear in the universe? A new study suggests that water may have formed ...

There are methods to generate hydrogen more efficiently, though, in a clean and sustainable process. that also produces useful heat and oxygen as byproducts. The key to the process? Concentrated ...

Metals can react with water, acid and oxygen. The reactivity of the metal determines which reactions the metal participates in. When metals react with water, metal hydroxides and hydrogen gas are ...

Researchers have developed a simple, sustainable and economic way to make the common household and industrial chemical, ...

Some chemical reactions change temperature ... a chemical in the yeast causes a reaction in which the hydrogen peroxide breaks apart to form oxygen gas and water. The oxygen was in the bubbles you saw ...
