Final answer:
Hazardous chemicals and radioactive materials require special handling, further analysis, proper disposal, and chemical testing.
Step-by-step explanation:
Two substances that would require special handling, further analysis, proper disposal, and chemical testing are hazardous chemicals and radioactive materials.
Hazardous chemicals, such as corrosive acids or toxic solvents, require special handling to ensure the safety of individuals and the environment.
They may also need further analysis to determine their composition or potential dangers.
After their use, they often need proper disposal to prevent harm.
Radioactive materials, such as isotopes of carbon or other radioactive elements, also require special handling due to their potential hazards.
They may need further analysis to determine their radioactivity levels or other properties. These materials require proper disposal to prevent contamination.
