Question

question 10 1 pts a molecule that is polar: can form a hydrogen bond. must be ionic. has an unequal charge. is both a and c. question 11 1 pts the elements carbon, hydrogen, oxygen, and nitrogen make up which percentage of the human body? 50% 69% 78% 96% question 12 1 pts hydrogen bonds result from unequal charge distribution on a molecule. such molecules are said to be nonpolar. polar. covalent. ionic.

Explanation:

• Question 10: Polar molecules have an unequal charge distribution and can form hydrogen - bonds. They are not necessarily ionic.
• Question 11: The elements carbon, hydrogen, oxygen, and nitrogen make up about 96% of the human body.
• Question 12: Molecules with unequal charge distribution that can form hydrogen - bonds are polar.

Answer:

• Question 10: D. is both A and C.
• Question 11: D. 96%
• Question 12: B. polar
