QUESTIONS AND CORRECT
VERIFIED ANSWERS/WELL ANALYSED ALL GRADED A+
Definition of biochemistry - CORRECT ANSWER-chemistry of life; how
properties of organisms relate to their molecules
What are the 3 things biochemists study? - CORRECT ANSWER-1. The
relationship between structure and function of biomolecules
2. Chemical reactions of organisms (metabolism)
3. Communication within and among organisms
What is the "medium" of life and why? - CORRECT ANSWER-Water, it is found
in all cells and multicellular organisms
, What is the shape and bond angle of water? Explain its bond angle - CORRECT
ANSWER-Water is shown in a BENT structure with 104.5 degree bond angle
due to the repulsion of electrons in chemical bonds.
Name the four common molecular shapes of simple compounds, their bond
angles, and their common description - CORRECT ANSWER-Linear: 180
degrees, common in CO2 and triple bonds
Trigonal Planar: 120 degrees, common with double bonds
Trigonal Pyramidal: 107.5 degrees, common in nitrogen atoms
Tetrahedral: 109.5 degrees, common with carbon atoms with all single bonds
What is organic chemistry? - CORRECT ANSWER-focuses on chemical and
physical properties of carbon compounds
What is inorganic chemistry? - CORRECT ANSWER-focuses on metals,
minerals, and other non-organic compounds
What is carbon's nickname? - CORRECT ANSWER-superglue of chemical
world
What does carbon have the ability to? - CORRECT ANSWER-ability to form
stable covalent bonds in unique combination
Describe the properties of carbon (5) - CORRECT ANSWER--Has 4 valence
electrons permitting it to form 4 bonds
-Forms long chains of carbons (polymers)
-forms double and triple bonds
-forms cyclic compounds
