to make 250.0L of hydrogen gas: how many moles of water would need to react and how many moles of oxygen would be produced?

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom

High-energy and unstable.

Polymerization reaction

The answer this would be radiative zone
