Question

What is hydrogen and oxygen​

Answer 1

Answer:

hydrogen oxygen

Explanation:

When molecular hydrogen (H2) and oxygen (O2) are combined and allowed to react together, energy is released and the molecules of hydrogen and oxygen can combine to form either water or hydrogen peroxide. ... In this oxidation, a molecule of hydrogen gas is ionized to two electrons and two protons.

Answer 2

Answer:

Hydrogen peroxide is a chemical compound with the formula H ₂O ₂. In its pure form, it is a very pale blue liquid, slightly more viscous than water. It is used as an oxidizer, bleaching agent, and antiseptic.

Formula: H2O2

IUPAC ID: hydrogen peroxide

Molar mass: 34.0147 g/mol

Density: 1.45 g/cm³

Boiling point: 150.2 °C

Melting point: -0.43 °C

When molecular hydrogen (H2) and oxygen (O2) are combined and allowed to react together, energy is released and the molecules of hydrogen and oxygen can combine to form either water or hydrogen peroxide. ... Chemists use redox half-reactions to describe thermodynamic processes like the ones embodied by such equations
