Question

1. fireworks are primarily made of charcoal (solid carbon) that causes them to explode. a firework technician would need a knowledge of which branch of chemistry?

analytic chemistry
inorganic chemistry
organic chemistry
biochemistry

Explanation:

To determine the relevant branch of chemistry for fireworks (made of charcoal, solid carbon), we analyze each option:

• Analytic chemistry focuses on analyzing substances (not about carbon - based compounds in fireworks).
• Inorganic chemistry deals with non - carbon - based or simple carbon - containing compounds (like carbon in elemental form as in charcoal, which is relevant for fireworks' explosive reactions).
• Organic chemistry is about carbon - containing compounds with C - H bonds (charcoal is elemental carbon, not organic in the typical organic chemistry sense).
• Biochemistry deals with biological molecules (not relevant for fireworks).

So the relevant branch is inorganic chemistry.

Answer:

B. Inorganic chemistry (assuming the options are labeled as A: analytic chemistry, B: inorganic chemistry, C: organic chemistry, D: biochemistry)
