What is the structure of hydrogen peroxide?

The chemical formula for hydrogen peroxide is H 2 O 2. It is often referred to as water with one more oxygen atom. It is acidic in nature and PH is about 4.5. It is 100 percent degradable compound. The structure of hydrogen peroxide is non-planar. H 2 O 2 has an open book structure with O O spins. The dihedral angle is 111°.See all results for this questionWhat is the composition of orthohydrogen gas?The orthohydrogen form has parallel spins; the parahydrogen form has antiparallel spins. At standard temperature and pressure, hydrogen gas consists of 75 percent orthohydrogen and 25 percent parahydrogen.See all results for this questionWhat are the properties of a hydrogen atom?The Hydrogen Atom Many of the hydrogen atoms chemical properties arise from its small size, such as its propensity to form covalent bonds, flammability, and spontaneous reaction with oxidizing elements. Hydrogen gas (H 2) is highly flammable and will burn in air at a very wide range of concentrations between 4 percent and 75 percent by volume.See all results for this question

Properties of Hydrogen | Introduction to Chemistry

Hydrogen has a melting point of -259.14 °C and a boiling point of -252.87 °C. Hydrogen has a density of 0.08988 g/L, making it less dense than air. It has two distinct oxidation states, (+1, -1), which make it able to act as both an oxidizing and a reducing agent. Its covalent radius is 31.5 pm.Phenobarbital | C12H12N2O3 - PubChemPhenobarbital is a long-acting barbituric acid derivative with antipsychotic property. Phenobarbital binds to and activates the gamma-aminobutyric acid ()-A receptor, thereby mimicking the inhibitory actions of GABA in the brain.
