Hi there! Well, to answer your question, chemical reactions invlove two sets of substances: the reactants and the products. The reactants are the chemicals that are involved BEFORE the reactions occurs. The products are the chemicals that are formed as a result of the chemical reaction. In another words, the products are your end results. Therefore, chemicals reactions make new materials called the PRODUCTS, rather than reactants. For example in photosynthesis:
Glucose + Oxygen -----> Carbon dioxide + Water
Glucose and oxygen are your reactants, whereas carbon dioxide and water are your products.
In a chemical reaction the actual reactants are also called the starting materials or interactants. These are the materials necessary for the reaction to happen and undergo chemical change.
The rearranging of the chemical make-up of matter is called a chemical reaction. This is what will constitute a chemical change as it will alter the chemical composition.
Metabolism and/or catabolism.
before reaction = reactants after reaction = products
Chemical changes occur when a substance combines with another to form a new substance, called synthesis or, alternatively, decomposes into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. Some reactions produce heat and are called exothermicreactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. Understanding chemical changes is a major part of the science ofchemistry. When chemical reactions occur, the atoms are rearranged and the reaction is accompanied by an energy change as new products are generated. An example of a chemical change is the reaction between sodium and water to produce sodium hydroxide and hydrogen. So much energy is released that the hydrogen gas released spontaneously burns in the air.
The starting materials in a chemical reaction are called reactants.
Substances that are changed when they become involved in chemical reactions are called reactants. These reactants are changed into new substances that are called products.
Reactants are substances that are changed when they become involved in chemical reactions. Products are the new substances that are formed.
Reactants
In a chemical reaction the actual reactants are also called the starting materials or interactants. These are the materials necessary for the reaction to happen and undergo chemical change.
The initial substances in a chemical reaction are called reactants.
Chemical reactions turn chemicals called reactants into chemicals called products.
In a chemical reaction, the starting materials are called the reactants.
The substances you have at the beginning of a chemical reaction are called the reactants.
These substances are called reactants.
The type reaction that changes the reactants into products is called a chemical reaction. Most chemical reactions can run forward or backward.
These substances are called reactants.
