Elements.
1. A pure substance can not be separated farther since it is composed of one type of atom. 2. I can't define mechanical mixture... Check your text book 3. A solution is one or more substances. I can: As she said a pure substance has only one type of particle. A solution is MORE then one substance. But in a solution u can't see the different parts. In a mechanical mixture, there is more then one particle like in a solution, but u can see the different particles.
it all depends on how high of a dose and what type of controlled substance.
Carbon, Hydrogen, Oxygen. Essentially a cellulose-type hydrocarbon
No. Porcelain is a man-made substance made from clay and fired in a kiln.
It is known as an element. An element is a substance that is made up of only one type of atom, characterized by a unique atomic number on the periodic table.
All elements in the Periodic Table contain only one type of atom.
only contains one atom
No, it contains many compounds and elements mixed in any ratio. It contains humus, and other particles including dirt. It is a mixture. A pure substance must contains only one type or atom (Element) or one type of molecule (compound).
Potassium metal is a pure substance. In fact, it is an element as well. The reason potassium metal is an element is that it only contains one type of atom (all atoms of potassium have the same number of protons).
Element
A compound is a substance that contains multiple types of atoms chemically bonded together. Examples include water (H2O) and carbon dioxide (CO2).
An element contains only one type of atoms. the substance which is made of more than one type of atom is called COMPOUND.Read more: Is_an_element_made_out_of_more_than_one_type_of_atom
all
The substance that consists of only one type of atom is best exemplified by elements on the periodic table, such as gold (Au), oxygen (O), or carbon (C). Each element is made up of only one type of atom, which cannot be broken down chemically into simpler substances.
