An open-end manometer containing mercury is connected to a container of gas, as depicted in Sample Exercise 10.2 in the textbook. What is the pressure of the enclosed gas in torr in each of the following situations? Part A: The mercury in the arm attached to the gas is 15.0 cm higher than in the one open to the atmosphere; atmospheric pressure is 0.975 atm . Part B: The mercury in the arm attached to the gas is 12 mm lower than in the one open to the atmosphere; atmospheric pressure is 0.97 atm.

For cyclohexane compounds drawn in a chair conformation:   -axial bonds are vertical  -equatorial bonds are parallel to two bonds within the ring.  thus, as i assume the chair conformation is drawn:   -the x group is in an axial position, as are the five other vertical bonds.  -three axial bonds are on the top face of the ring  -the other three axial bonds are on the bottom face  the position of the second substituent on each ring carbon is equatorial.  gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other.  drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1.  click this link and watch some academic videos that may you more understand the topic 

Hey how did you manage to type such a big lab report

Ithink 2 is the correct

Sorry i dont understand the question can you rephase it?
