Why do you think water and hydrogen peroxide have different chemical properties?

Why do you think water and hydrogen peroxide have different chemical properties?

But because they have different molecular structures, they have very different chemical properties: water is a stable molecule, while hydrogen peroxide is unstable due to the bond between the two oxygen atoms (this is why over time, hydrogen peroxide will give off oxygen gas and turn into plain old water).

Why is hydrogen peroxide different from water?

Water and hydrogen peroxide are made of the same elements: oxygen and hydrogen. However, hydrogen peroxide (H2O2) has 1 more oxygen than water (H2O).

What are the physical and chemical properties of hydrogen peroxide?

Overview of H2O2 – Hydrogen Peroxide

Hydrogen peroxide Chemical formula	H2O2
Molecular Weight/ Molar Mass	4.0147 g/mol
Density	1.05 g/cm3
Boiling Point	150.2 °C
Melting Point	-0.43 °C

What causes elements to have different physical and chemical properties?

Each element within a group has similar physical or chemical properties because of its atom’s outermost electron shell (most chemical properties are dominated by the orbital location of the outermost electron).

What is the difference between hydrogen peroxide and peroxide?

The key difference between peroxide and hydrogen peroxide is that peroxide is an anion whereas hydrogen peroxide is a chemical compound. Peroxides are a special category of oxygen compounds with unique properties. Hydrogen peroxide was discovered by the French scientist Thenard in 1818.

How is water different from hydrogen peroxide even though both compounds are composed of only hydrogen and oxygen?

How is water different from hydrogen peroxide even though both compounds are composed of only hydrogen and oxygen? Although water and hydrogen peroxide are composed of only hydrogen and oxygen, the ratio of hydrogen atoms to oxygen atoms is 2 to 1 in water and 2 to 2 in hydrogen peroxide.

How do the physical properties of water and hydrogen peroxide compare?

Its physical properties are very similar to those of water, except that it is 40% denser. The main difference between hydrogen peroxide and water, however, is in its chemical behaviour. The single bond between the two oxygen atoms is weak, so that H2O2 readily fragments into either H and HO2 or two OHs.

What is physical properties of hydrogen?

At standard temperature and pressure, hydrogen is a nontoxic, nonmetallic, odorless, tasteless, colorless, and highly combustible diatomic gas with the molecular formula H2. Hydrogen is also prevalent on Earth in the form of chemical compounds such as hydrocarbons and water.

Why do different physical things have different physical properties?

The difference in the number of protons and neutrons in atoms account for many of the different properties of elements. They are the glue that holds atoms together in chemical bonds. The basic electron number is determined by the number of protons.

How does hydrogen peroxide react with water?

Hydrogen peroxide reacts very fast. It will than disintegrate into hydrogen and water, without the formation of byproducts. This increases the amount of oxygen in water….Disinfectants Hydrogen peroxide.
