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 are the elements or compounds that initiate a reaction whereas products are the elements or compounds formed from reaction. However, some reactions are reversible an â¦ d the reactants can become products and visa versa. This is most common in equilibrium instances with buffer solutions.n a chemical reaction, the reactants are the elements or molecules involved in producing a reaction. The products are the final outcomes of the chemical reaction. Example â¦. 2 people found this useful.
