Water is a chemical because it is made of matter. Matter is any object that takes up space and has mass. Although water is a liquid, it still has mass and occupies space.
A chemical change is a process where two substances combine to form one or more new substances. This process is referred to as a chemical reaction, and it is not reversible.
The systematic names for water, as determined by the International Union of Pure and Applied Chemistry (IUPAC), are water and oxidane, although water is the more commonly used term by chemists. The traditional name has been retained for ease of communication.
A chemical property is a characteristic associated with a substance or reaction that is observable as it chemically changes or transforms into another substance. This chemical change produces a product that has a different composition than the original substance.
Sugar is the name of a group of organic compounds such as glucose, fructose and sucrose. Each of these compounds can be expressed by its own unique chemical formula, almost always as CnHnOn, where "n" is often a number between 3 and 7.
Examples of a chemical change include rusting iron, burning wood, frying an egg and baking a cake. A chemical change occurs when the chemical composition of a substance changes irreversibly.
Burning, or rather combustion, leaves you with a different material than the one with which you started. A chemical change occurs if a new substance is created and most of the time cannot be reversed.
Ammonia is the chemical name for the molecular formula NH3, which is a compound of nitrogen and hydrogen. It is also known by the name azane.
According to Education Portal, chemical potential energy is any stored energy that has the potential to do work in the future. All physical matter has molecules that contain potential energy.
The chemical formula for chlorine is Cl2. This diatomic molecule is formed by two chlorine atoms. The bonding between these two atoms is weak, making the chlorine molecule highly reactive.
