PORTAGE LEARNING CHEM 210 MODULES
1–8 ACTUAL EXAM SCRIPT 2026
QUESTIONS AND SOLUTIONS GRADED A+
◉Smaller elements are favored because they can form stable
covalent bonds. T or F. Answer: True. Strong bonds form by
significant overlap of atoms, such as carbon and hydrogen, allowing
them to share electrons.

◉What is carbon referred to in the chemical world?. Answer: The
superglue
, ◉What does organic chemistry study?. Answer: Focuses on the
chemical and physical properties of carbon compounds
◉What does inorganic chemistry study?. Answer: The field dealing
with metals, minerals, and other non-organic compounds
◉How many bonds can a Carbon form?. Answer: 4! Due to having 4
valence electrons
◉What is a long chain of carbons called?. Answer: Polymers
◉What is a cyclic compound?. Answer: Carbons joined together in a
closed chain
◉What are carbon compounds called?. Answer: Alkanes
◉Condensed structures give a better idea of a molecules structure,
compared to chemical formula. T or F. Answer: T
◉Structural formula gives an even better idea of a molecules
structure, compared to chemical formula. Answer: T
