The Branches of Chemistry

What is the primary focus of analytical chemistry?

• Studying chemical processes in living organisms.

• Analyzing and identifying the chemical components of a sample.

• Investigating elements and compounds without carbon-hydrogen bonds.

• Transforming raw materials into beneficial products.

Determining how much caffeine is in a cup of tea is an example of:

• qualitative analysis
• quantitative analysis
• subjective assessment
• caffeine content estimation

Forensic science often uses which branch of chemistry?

• Analytical chemistry
• Biochemistry
• Physical chemistry
• Organic chemistry

What is the difference between quantitative and qualitative chemical analysis?

• Quantitative analysis identifies the types of substances present, while qualitative analysis measures their amounts.
• Both quantitative and qualitative analyses measure the same properties of a substance.
• Quantitative analysis is only used for solid substances, while qualitative analysis is for liquids.
• Quantitative analysis measures how much of a substance is present, while qualitative analysis identifies what substances are present.

Which of the following is NOT a sub-discipline of biochemistry mentioned?

• Enzymology

Biochemistry is best described as the study of:

• the effects of drugs on the body
• the classification of living organisms
• the chemical processes and substances in living organisms
• The synthesis of new drugs in factories

• study of radioactive chemicals

The study of hormones in living systems is called:

• biochemistry
• physiology
• cytology
• endocrinology

The process of photosynthesis is linked to:

• Organic chemistry.

• Biochemistry

• Nuclear chemistry

• Industrial chemistry

What type of compounds does organic chemistry primarily focus on?

• Compounds without carbon-hydrogen bonds.

• Elements found in minerals and metals.

• Carbon compounds and chemicals in living organisms.

• Radioactive nuclei and their properties.

Inorganic chemistry primarily studies substances that are considered:

• Living organisms and their chemical processes.

• Carbon-based compounds like fuels and plastics.

• Non-living materials and compounds without carbon-hydrogen bonds.

• Elements influenced by changes in atomic nucleus structure.
