What is a pure substance? A pure substance cannot be separated into any other kinds of matter by any physical or chemical process. It is also made up of the same particles. An element is an example of a pure substance because it cannot be broken down into simpler substance. Examples of pure substances would be: H2O (water), neon (an element), and NaCl (table salt). A pure substance cannot be separated into any other kinds of matter by any physical or chemical process.

What do you call a molecule made up of two elements? A molecule is two or more atoms chemically joined together. If at least two different elements make up the molecule, it is called a compound. For example, hydrogen gas (H2) and water (H2O) are molecules, but water is also a compound because it is made up of hydrogen and oxygen.f at least two different elements make up the molecule, it is called a compound. For example, hydrogen gas (H2) and water (H2O) are molecules, but water is also a compound because it is made up of hydrogen and oxygen.

Questions and Answers A molecule is what you get when any atoms join together. A compound is what you get when atoms of two or more different elements join together. All compounds are molecules, but not all molecules are compounds. Water is a molecule because it is made from atoms that have been chemically combined. It is also a compound because the atoms that make water are not all the same - some are oxygen and some are hydrogen. Oxygen in the atmosphere is a molecule because it is made from two atoms of oxygen. It is not a compound because it is made from atoms of only one element - oxygen. This type of molecule is called a diatomic molecule, a molecule made from two atoms of the same type.

- Chemical substances are often called 'pure' to set them apart from mixtures. A common example of a chemical substance is pure water; it has the same properties and the same ratio of hydrogen to oxygen whether it is isolated from a river or made in a laboratory. chemical substance is a form of matter that has constant chemical composition and characteristic properties. It cannot be separated into components by physical separation methods, i.e., without breaking chemical bonds. Chemical substances can be chemical elements, chemical compounds, ions or alloys.

Cost of raising children in UK higher than ever It means the average UK parent will have to spend more than a third (38%) of their take-home pay just to be able to afford one child, with the costs highest between the ages of one and four years old. In a child’s first year, parents will spend £11,498, rising to £63,224 between one and four. They then get a mild breather, with children between 5 and 17 costing an average of £8,640 a year. Then comes the shock of higher education costs, with the average 18 to 21-year-old costing their parents £17,815 a year.

- It is a mixture containing sugar particles and water particles. A mixture is a type of matter that contains more than one kind of particle. A mixture is made of two or more pure substances mixed together (Figure 3(b)). piece of aluminum foil contains only one kind of particle. Each aluminum particle is the same as every other aluminum particle. White table sugar is made of only sugar particles.Aluminum and table sugar are both examples of pure substances.

Why elements and compounds are called pure substance but not mixture? Report Abuse. Pure substances r those substances which r made of only one kind of PARTICLES. Now these particles can be ATOMS OR MOLECULES. Elements r considered to be pure b'coz it has same kind of atoms which cannot be seperated into simple other substances. For ex. a pure copper metal has only copper atoms (Cu) in it. Compounds r two or more elements combined together chemically. They have the same kind of molecules throughout. For e.g. Water is a pure substance as it's having only H2O molecules (one kind of particle).

What is a Substance? - Definition, Types & Examples In other words, a substance is matter than contains only one type of atom or molecule. Pure substances can be further divided into two sub categories: elements and compounds. Elements are the simplest form of matter, which means they cannot be broken down into smaller components physically or chemically.

What is one difference between a mixture and a compound? In a Compound, two substances combine to form a third substance (that replaces the two original substances) that is chemically different from the two original substances. In a Mixture, two substances are just mixed together (kind of like a salad), with each of the two original substances retaining its own chemical properties; and no third substance is formed.

Questions and Answers Atoms are the smallest bits of ordinary matter and are made from particles called protons (which carry a positive electrical charge), neutrons (which carry no electrical charge) and electrons (which carry a negative electrical charge). An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing just one proton and one electron. If you had very, very good eyes and could look at the atoms in a sample of hydrogen, you would notice that most of the atoms have no neutrons, some of them have one neutron and a few of them have two neutrons.
