Final answer:
The chemistry lab accident involving nickel hydrazine perchlorate can be attributed to chemical contamination. It's important to maintain proper safety precautions in the laboratory to avoid accidents.
Step-by-step explanation:
The chemistry lab accident involving nickel hydrazine perchlorate can be attributed to chemical contamination. Chemical contamination refers to the presence of unwanted substances or impurities in a chemical reaction or laboratory setting. In this case, if the nickel hydrazine perchlorate was contaminated with another reactive substance, it could lead to an explosion.
It's important to maintain proper safety precautions in the laboratory, such as ensuring adequate ventilation, proper storage of chemicals, and following guidelines for handling hazardous materials. Accidents can occur when these safety measures are not followed, resulting in avoidable incidents.
In the case of the given options, option C) Chemical contamination is the most likely cause of the nickel hydrazine perchlorate explosion.
