Reference checking is a vital part of a successful hiring strategy1 and is primarily used to: â¢ Verify information provided by the candidate. â¢ Better predict the candidateâs on-the-job success. â¢ Gain additional knowledge (e.g., candidateâs abilities) Reference checking aims to verify the information a candidate provided (e.g., resume) and can. provide a different perspective. Both instances present a better picture to the hiring manager of. how the candidate would perform on the job.
The substance (or substances) initially involved in a chemical reaction are called reactants or reagents. Chemical reactions are usually characterized by a chemical change, and they yield one or more products, which usually have properties different from the reactants.he general concept of a chemical reaction has been extended to reactions between entities smaller than atoms, including nuclear reactions, radioactive decays, and reactions between elementary particles as described by quantum field theory.

They can join up with atoms of the same element or with atoms of different elements. Substances whose molecules contain different types of atom are called compounds.Chemical reactions can CHANGE MOLECULES and when this happens, new molecules and therefore new compounds are formed.n a covalent bond, electrons are shared between two atoms. When two oxygen atoms bond together to form an oxygen molecule, they share four electrons â two from each oxygen atom. Other examples of covalent bonding are water (H 2 O), and carbon dioxide (CO 2).
