Main uses

Hydrogen Peroxide: One main use for hydrogen peroxide is it's used as a disinfectant.

Manganese Dioxide: A main use of manganese dioxide is dry-cell batteries such as alkaline batteries.

Physical Properties of Manganese Dioxide (MN02).

Quantitative Physical Properties of Water

Chemical Reaction of Hydrogen Peroxide and Manganese Dioxide

Chemical Property

Chemical Properties of Manganese Dioxide

Boiling Point- 100 degrees celcius

Sollubility- Soluble

Density- 1 g/cm3

Quantitative Property: A physical property that can be measured and assigned a particular value.

A chemical property is the ability of a substance to change or react, and to form new substances.

Oxidation- it is already fully oxidized

Combustibility- Isn't combustible because it's already fully oxidized

Reaction with an Acid- ph level of 3-10.

Equations of Reaction

Viscosity- 1.245

Melting Point- -0.43 degrees celcuis

Boiling Point- 150.2 degrees celcius

Solubility- miscible

Density- 1.135 g/cm3

What is a Physical Property?

2h20+Mn02----->2H20+02

Hydrogen Peroxide+Manganese Dioxide (reacts to produce) Water+ Oxygen

Qualitative Properties

A physical property is a characteristic of a substance that can be observed and measured without changing the identity of the substance.

This is Hydrogen Peroxide before reaction (H202).

Chemical Properties Of Hydrogen Peroxide

Physical Properties of Hydrogen Peroxide

Reaction Between Hydrogen Peroxide and Manganese Dioxide

Colour- Black

Odour- Odourless

State- Solid/powder

Lustre- Dull

Malleability- Not malleable

Texture- Powder

Qualitative Property: A physical property that can be described but not measured.

Manganese Dioxide

Quantitative Properties of Oxygen

Oxidation- It is a strong oxidizer, and used as a disinfectant

Combustibility- if comes into contact with physical or mechanical disturbances, will become flammable

Reaction with an Acid- the accidity is 11.65 and decomposes into water and oxygen.

Colour- Colourless/clear

Odour- Strong, smells like vinegar and slightly sharp

State- Liquid

Physical Properties of Water

Qualitative

Thanks for watching! :)

A picture of the reaction

Chemical Properties of Oxygen

Melting Point- -218.8 °C

Density- 1.331 kg/m3

Qualitative Physical Properties of Oxygen

Catalyste- increase of a rate of a chemical reaction due to participation of an additional substance.

The Manganese Dixoide is the catalyst in this reaction. It helps the Hydrogen peroxide to react. The Manganese Dioxide remains the same before abnd after the reaction.

Colour- Colourless

Odour- Odourless

State- Liquid

Oxidation- Does not oxidize

Combustibility-Doesn't combust

Reaction with an Acid- Oxygen doesn't react with most acids.

Colour- Colourless

Odour- Odourless

State- Gas

Quantitative Properties

Melting Point- 535 degrees celcius (decomposes)

Solubility- Insoluble

Hardness- Not hard

Density- 5.026 g/cm3

Chemical Properties of Water

Oxidation- Does not Oxidize

Combustibility- Doesn't Combust

Reaction with an Acid-Water has a neutral accidity

Referances

In conclusion, the Hydrogen Peroxide decomposes to water and oxygen. The manganese is used to increase the rate of reaction in the Hydrogen Peroxide.
