A chemical substance is a material with a specific chemical compound.
A common example of a chemical substance is pure water; it has the same properties and the same ratioof hydrogen to oxygen whether it is isolated from a river or made in a laboratory. Some typical chemical substances are diamond, gold, salt (sodium chloride) and sugar (sucrose). Generally, chemical substances exist as a solid, liquid, or gas, and may change between these phases of matter with changes intemperature or pressure. Chemical reactions convert one chemical substance into another.
Forms of energy, such as light and heat, are not considered to be matter, and thus they are not "substances" in this regard.

Where does the chemical combination of substances take place?
The chemical combination of substances primarily occurs in chemical reactions, which can take place in various environments such as laboratories, industrial settings, or naturally occurring processes. These reactions can happen in solids, liquids, or gases and often require specific conditions like temperature, pressure, and the presence of catalysts. In biological systems, chemical combinations are fundamental to metabolic processes, occurring within cells.
What are reactant products?
reactants- the substances that take part in a chemical reactionproducts- the new substances formed after a chemical reaction
What has to take place in order for chemial bonds to break and new bonds to form?
energy must be addedSolids must be dissolved
Why do substances take place in a chemical reaction?
Substances undergo chemical reactions due to the breaking and forming of chemical bonds, which occurs when atoms rearrange to create new substances. This process is driven by factors such as energy changes, stability, and the tendency to achieve a lower energy state. Additionally, reactions can be influenced by factors like concentration, temperature, and the presence of catalysts, which can accelerate or facilitate the reaction. Overall, chemical reactions are fundamental to transforming materials and creating diversity in chemical compounds.

Do chemical changes take place when a mixture is made?
No!chemical changes do not take place when a mixture is made.The constituent substances of the mixture retain their own chemical composition.Thus only physical changes take place.
What are facts about physical and chemical change?
Chemical changes take place on the molecular level

Substances that are about to take part in a chemical reaction?
Reactants are the substances that are about to take part in a chemical reaction. These are the elements or compounds that are present at the beginning of the reaction and typically undergo a change during the process.
