Consider the following set of requirements for a university information system that is used to keep track of students’ transcripts.

R1: The university keeps track of each student's name, student number, class, and degree program.

R2. The university consists of various departments. Each department is described by a name, department code and phone.

R3. Each course has a course number, course name, and credits.

R4. Each section has an instructor, course number, and section number. There might be multiple sections of each course offered in the semester.

The other requirements for this application are:

R5: An administrator can update the courses to be taught by instructors, and enter the list of students taking a course.

R6: An instructor can enter and update the grades of the course(s) taught by this instructor.

R7: A student can request a grade report from the information system.

The use of a true experimental research design in empirical research is usually not applicable when ______. 1. participants cannot be randomly allocated to groups 2. it is expensive to transport participants to the laboratories 3. it is difficult to find willing individuals to participate 4. strict control measures are put in place throughout the research

A 7.364 gram sample of an organic compound containing only C, H, and O is analyzed by combustion analysis and 9.343 g CO₂ and 2.550 g H₂O are produced.

In a separate experiment, the molar mass is found to be 104.1 g/mol. Determine the empirical formula and the molecular formula of the organic compound.

A steel cylinder contains 6.812×10⁻³ kg of an unknown gas. Combustion analysis indicates that the gas has the empirical formula CH4. The volume of the cylinder is 2.20×103mL, and the pressure inside the cylinder is 3.6×103mmHg. The cylinder is stored in a closet at 25.0 ∘C.

What is the molecular formula of the gas?

When 0.25 g of Na combines with elemental oxygen under certain conditions, it forms 0.42 grams of a binary compound Na_xO_y - made of Na and O atoms only. Find its empirical formula:

Find its molecular formula, given its molar mass of 78g/mol:

Could you please do a unit analysis on Riedel and Antoine equation to determine the units of the empirical coefficients. Pressures in kPa and temperatures in Kelvin.

Riedel equation : lnP(T) = Ar + Br/T + Cr.ln(T) + Dr.T6

Antoine equation: lnP(T) = Aa - Ba/(Ca+T)
