Answer:
You could check the pH!
Explanation:
This is an idea, when you break down H2O2 (Hydrogen peroxide) you will be left with H2O (Water) and O2 (Oxygen gas). H2O2 theoretically would have a lower pH than water. Water has an average pH of around 7 while H2O2 will have a pH of about 4.5.
So theoretically to figure out if hydrogen peroxide is being broken down you can test for the pH. This is a very simply process, you just stick a little peice of litmus paper into the solution and immediatly it will change color to tell you the pH.
The correct match is
Atom: A) the basic unit of an element.
Atom is the smallest and structural unit of any element.
Particle: D) a tiny fragment or piece of matter.
A particle can be defined as a minute or small piece, fragment or portion of any matter. It may be used to access many physical and chemical properties such as density, volume, mass etc.
Phase: C) unique form of matter in which it can exist.
Phase can be defined as a particular state in which any matter can exists. Generally, matter can exists in three phases namely; solid, liquid, and gas. Plasma is the fourth phase which exists at very high temperature and pressure.
Scientific theory: B) an explanation for some naturally occurring event.
Scientific theory can be explained as a group of postulations or hypothesis formulated in order to explain naturally occurring phenomenon or event. These hypothesis are repeatedly confirmed with the help of experiments or observations.

Vitamin E is an example of a a fat soluble vitamin together with vitamins A, D and K. It is carried to the liver and other tissues by lipoproteins. Vitamin E functions to protect phospholipids in cell membranes from damage by free radicals. It is also important to note that a high intake of vitamin E can interfere with vitamin K's blood clotting activity.
