Classify what type of reaction occurred for hydrogen peroxide (there are 5 types you learned): A decomposition reaction occurred
due to its characteristics. These characteristics are when a chemical change breaks down a compound into one or two simpler compounds, which in this case were water and gas.
1 answer:
Answer:
A Reaction of decomposition is ocurred to hydrogen peroxide.
Explanation:
Hydrogen peroxide is a molecule that can break down into Hydrogen and Oxygen or decompose very slow under moderate temperature, as you can see in the image below, hydrogen peroxide has a high electronic cloud that makes it a great oxidizer.

The substance which has mass and volume is said to be matter. Matter is classified as Pure substance (Element and Compound) and Mixture (Homogeneous and heterogeneous).
The simplest form of matter that has unique properties is known as element.
Elements can't break down into simpler units or substances by physical or chemical process. It is a pure substance which is made up of single type of atom such as hydrogen is made up of hydrogen atoms only.
Every element has unique name and symbol such as name: iron and its symbol is .
Hence, element is defined as the simplest form of matter that has unique properties.
