Innumerable examples occur. From apple juice to the very elements themselves. Fruit juice is a compound of many materials.

Many elements have isotopes - Tin has almost 30 isotopes - most non natural. Sulfur has four natural ones, and even hydrogen has a couple of natural isotopes.

A pure substance is an example of a homegenous mixture that is very evenly mixed. is that right?

A pure substance and a homogeneous mixture are two different things. A pure substance is anything that is completely by itself. (An element, pretty much) A homogeneous mixture is a mixture of 2+ compounds that you can not differentiate the separate substances in the product. Such as soda, it is all one color and one texture, but there are many compounds in it.

What are the different characteristic of matter?

Matter can be classified as a pure substance or a mixture. Pure substances are made of only one type of atom or molecule, while mixtures contain two or more different substances physically combined. Matter also has properties like mass, volume, and density, and can exist in different states - solid, liquid, gas, or plasma - depending on the arrangement of its particles.


When a physical changes occurs new substance are formed?

False. In a physical change, the substance remains the same even though there may be a change in appearance or state. The molecules of the substance do not rearrange themselves to form a new substance.
