The substances present before a chemical reaction are called reactants. These are the starting materials that undergo a transformation to form new products during the reaction.
After a chemical reaction, the materials present can include reactants, products, byproducts, and any leftover starting materials that did not react. The specific materials depend on the reactants used and the conditions of the reaction. Analytical techniques such as chromatography, spectroscopy, and mass spectrometry can help in identifying the various materials present after a reaction.
The mass of all substances before a chemical reaction is equal to the mass of the substance after the reaction. This is under the law of conservation of mass.
When a chemical reaction takes place, it starts with chemicals which are called reactants, literally meaning those which react, and after the reaction has taken place you then have chemicals called products, because they were produced by the reaction.
The substances you have at the beginning of a chemical reaction are called the reactants.
True. In a chemical reaction, atoms are rearranged to form new substances, but the total number of atoms present before and after the reaction remains constant. This is known as the Law of Conservation of Mass.
Substances that are present before the reaction are called "reactants" or "reagents".

The reactants exist before a reaction begins, and also the products are the result of the reaction of the reactants.
These initial substances are the reactants.
The products of a chemical reaction are the substances that are formed as a result of the reaction taking place. These products can be different compounds or elements from the reactants that were present before the reaction occurred.

A catalyst does. These are usually non-organic substances that speeds up chemical reactions. The reactants are the ones that are present BEFORE the reaction.

When a chemical reaction takes place, it starts with chemicals which are called reactants, literally meaning those which react, and after the reaction has taken place you then have chemicals called products, because they were produced by the reaction.
That depends on the chemicals present before the chemical reaction and sometimes the conditions under which the chemical reaction occurred.
The initial substances in a reaction are called reactants.
