Q

How did German chemist Freidrich Wöhler borne biochemistry?

A

In 1828 he accidentally synthesized urea from inorganic precursors, which was previously thought to be impossible. Scientists didn’t think synthesizing organic compounds from inorganic compounds was possible.

Q

What is Inorganic Chemistry?

A

A branch of chemistry studying properties and behaviour of inorganic compounds.

18
Q

Differentiate between Inorganic Compounds and Organic Compounds.

A

Inorganic Compounds: Generally non-biological compounds lacking hydrogen + carbon bonds. CAN contain carbon
Organic Compounds: Consist of carbon + hydrogen and usually derived from living things

19
Q

What are some sub-branches of Inorganic Chemistry?

A

Geochemistry, physical chemistry (physicochemistry), bioinorganic chemistry, etc.

20
Q

What is Geochemistry?

A

Studying chemicals of planets and chemical compositions of rocks and soil.

21
Q

What is physical chemistry?

A

– AKA physicochemistry
– Relevant to virtually all other scientific fields and serves as foundation
– Relating to the concept of physics in chemical systems, using the principles of thermodynamics, quantum chemistry, and kinetics as its basis.

22
Q

What is Bioinorganic Chemistry?

A

– Studying compounds with metal-carbon bonds within biological systems.
– Focuses on the pretense of metal ions in biochemical processes. (?)
– Includes aspects of organic chemistry

23
Q

What are impacts of Inorganic Chemistry on daily life?

A

Education, environmental science, government agencies, formulas for household cleaners, etc.

24
Q

What four subject areas encompass physical chemistry?

A

Thermodynamics, quantum chemistry. chemical kinetics, statistical thermodynamics.

25
Q

What is Thermodynamics?

A

– Study of the conversion of energy into heat and work
– Studies ways in which the conversion process can be affected by changing variables (pressure, temperature, etc.) within a system.

26
Q

What is Quantum chemistry?

A

– Theoretical science describing how molecules bond to one another by applying principles of quantum field theory and quantum mechanics.
– These principles describe how atoms and subatomic behave in various systems and govern molecules’ behaviour.

27
Q

What is Chemical kinetics?

A

– Studies rates of chemical processes and how changing variables affect them

28
Q

What is Statistical thermodynamics?

A

– Studies energy distribution in chemical systems and links the microscopic and macroscopic worlds.
– Main objective is to interpret the macroscopic properties of various types of matter in relation to interactions b/w their constituent microscopic molecules and particles

29
Q

What are the interdisciplinary subdivisions of Chemistry?

A

– Descriptive Chemistry
– Environmental Chemistry
– Food Chemistry
– Nuclear Chemistry
– Drug Chemistry
– Petroleum CHemistry
– Radiochemistry
– Astrochemistry

30
Q

38
Q

What is Pseudoscience?

A

Beliefs/practices stated as factual but aren’t compatible with the scientific method

39
Q

What is Astrology?

A

– Pseudoscience with belief systems claiming a relationship between astronomical phenomena and events in the human world
– No scientific evidence to support it

40
Q

What is Alchemy?

A

– Pseudoscience historically practiced ancient proto-scientific tradition in China, India, the Muslim world + Europe.
– Significantly helped early scientific development but is no longer considered a field of science
