The correct answer is number 2 and shows the spontaneous breakdown of hydrogen peroxide into water and oxygen. Hydrogen peroxide is eventually going to break down into the water but because there isn't enough hydrogen, oxygen will also form. Hydrogen peroxide should never be consumed like water.

Even though it has similar properties and the same type of elements and similar molecules, it is NOT the same. Ingesting too much can be fatal and if consumed, several large glasses of water should be taken to dilute the chemical. Otherwise, hydrogen peroxide is safe and effective for treating cuts and scrapes.

The answer to this is number 2. 2H202 = 2H2O+O2. It is important that you know how to balance chemical equations to help you understand further why matter cannot be created and destroyed. 2H202 is actually the scientific formula for Hydrogen Peroxide. This is a type of substance that can be purchased in various stores.

This can be effective in cleaning various surfaces. It can also be used to clean wounds. While this can be used for cleaning and different purposes, you should never drink it as it can be unfavorable to the body. Having this around the house can be beneficial though.

Hydrogen peroxide is a substance that can be bought in the grocery store. It is used for different reasons including to clean anything that you would clean bleach with. The peroxide comes in a light blue color and it is liquid. Its formula is H2O2 which means that there are two oxygen molecules and two hydrogen molecules. If there are two hydrogen peroxide molecules, that means that two water molecules and two oxygen molecules came together.

Sometimes, hydrogen peroxide is used as a detergent to clean clothes or other materials. Peroxide is commonly used to bleach hair to a blonde color. Glow sticks use hydrogen peroxide to make these bright toys. You should never drink hydrogen peroxide as it is dangerous.
