Final answer:
Disinfectants and antiseptics are the chemical agents used to destroy bacteria and viruses on surfaces and combs.
Step-by-step explanation:
Chemical agents used to destroy bacteria and viruses on surfaces and combs are disinfectants and antiseptics. Disinfectants are used to reduce the number of microbes on inanimate surfaces, while antiseptics are used to reduce the number of microbes on living tissues. Antibiotics are drugs that are used to treat bacterial infections, not to kill bacteria on surfaces or combs. Vaccines are substances that stimulate the immune system to produce an immune response to a specific disease, and they do not directly destroy bacteria or viruses on surfaces.
