1 Time-Pathogenic bacteria need enough time in order to multiply. 2  The number of bacteria will reach dangerous levels very quickly in a short period of time in perfect conditions. 3  Keep in mind that bacteria can reproduce every 20 minutes in perfect conditions.
Nuclear chemistry is a sub-discipline of chemistry that involves the chemical reactions of unstable and radioactive elements where both electronic and nuclear changes may occur. 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.
Reactants vs Products. A reaction is a process of converting a set of substances into another set of substances. The substances at the beginning are known as reactants, and the substances after the reaction are known as products.roducts are the new substances formed after a reaction. They are formed by the reaction between reactants, and they have different characteristics than reactants. Products may have a lower energy or higher energy than the reactants.
