Question 5

If a student’s lab grade is below 60%, what is the consequence according to the course policy?

Accepted Answer

The student will be dropped from the course.

Question 6

Which formula is used to determine the percent yield of a chemical reaction?

Accepted Answer

$$	ext{Percent Yield} = \frac{	ext{Actual Yield}}{	ext{Theoretical Yield}} 	imes 100\%$$

Question 7

A student missed an exam due to a documented medical emergency. According to the makeup policy, what must the student do to be eligible for a makeup exam?

Accepted Answer

Submit documentation and take the makeup exam within the week.

Question 8

Which of the following best describes the role of intermolecular forces in determining the properties of substances?

Accepted Answer

They determine physical properties such as boiling point, melting point, and solubility.

Question 9

Which equation is used to relate the pressure ($$P$$), volume ($$V$$), temperature ($$T$$), and number of moles ($$n) of an $$ideal gas?

Accepted Answer

$$PV = nRT$$

Question 10

A student receives the following scores: Exam 1: 85, Exam 2: 90, Exam 3: 80, Final Exam: 75, Homework: 95, Lab: 88. If exams are 40%, final exam 25%, homework 10%, and lab 25% of the grade, what is the student’s overall percentage grade?

84.5%

Question 11

Which of the following is a correct statement about academic integrity in this course?

Accepted Answer

Cheating and plagiarism are strictly prohibited and may result in disciplinary action.

Question 12

Which formula is used to calculate the dilution of a solution, where $$M_1$$ and $$V_1$$ are the initial molarity and volume, and $$M_2$$ and $$V_2$$ are the final molarity and volume?

Accepted Answer

$$M_1V_1 = M_2V_2$$

Question 13

Which of the following is NOT permitted during exams according to the course policies?
