Question 1.
Which is a limitation of using cellulose?
A. its lack of mass production
B. its lack of biodegradability
C. its harm to landfills
D. its high cost to recycle
Question 2.
Which refers to a macromolecule that forms as a result of the joining of multiple monomers?
A. amino acid
B. glucose
C. nucleic acid
D. polymer
Question 3
What does the octet rule state that explains why atoms bond?
A. Atom bonds have eight valence electrons to become stable.
B. Atom bonds lose eight valence electrons to become stable.
C. Atom bonds have eight valence electrons to become unstable.
D. Atom bonds to lose eight valence electrons to become unstable.
Question 4
Shameeka is studying for an exam. She took the notes below about calcium and chlorine, which are known to form ionic bonds.
Calcium, which is a metal, donates 2 electrons to chlorine.
The individual calcium atoms become ions with a negative 2 charge.
The bond between calcium and chlorine makes the atoms stable.
Calcium and chlorine attract each other.
Which best describes Shameeka’s error?
A. Calcium is a metal, so it donates protons, not electrons.
B. The individual calcium atom has a positive, not negative, 2 charge.
C. The bond formed makes the atoms unstable, not stable.
D. Calcium and chlorine repel, not attract, each other.
