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.eactants vs Products.
