Two hydrogen atoms then bond to form hydrogen gas (H 2) and 2 oxygen atoms bond to form oxygen gas (O 2). Each water molecule has all the atoms needed to make 1 molecule of hydrogen gas. But with only ...

Hydrogen-powered cars have historically faced a lot of hurdles, including fueling challenges and pricing pressures. But Honda is counting on hydrogen to help it decarbonize its vehicle fleet by 2040.

A water molecule is made of one oxygen atom bound to two hydrogen atoms, hence its chemical formula: H 2 O. But that’s not the hydrogen they’re talking about.
