Question

Argue the benefit of chemistry to the field of forensic science, using a specific example.

Answer 1

Chemistry is often used in firearms crimes to identify information from recovered bullets and residue. For example, a forensic scientist will examine a suspect´s hands and clothes with infrared lights to look for gunpowder residue.

Step-by-step explanation:

Answer 2

A strong background in chemistry and instrumental analysis and a good grounding in criminalistics are vital. An undergraduate degree in forensic science or natural science is required for work in crime laboratories, with extensive coursework in mathematics, chemistry, and biology. More advanced positions, such as lab managers and supervisors, might require a master’s degree. A Ph.D. is often preferred for advancement to positions such as lab director, but it is required for forensic research positions at academic institutions. Arsonists, for example, often use accelerants such as gasoline or kerosene to speed combustion and spread flames in the interior of a building. A forensic chemist may collect samples of burned and unburned materials, extract the volatile hydrocarbons, and separate the components for analysis by gas chromatography.
