Ablock of metal is on a table. which must be true for thermal energy to flow from the table to the metal? a. both the table and the metal must be cooler than surrounding air. b. the metal must be cooler than the air. c. the table and the metal must be in thermal equilibrium. d. the table must be cooler than the metal.

Well, I haven't figured this out yet I am only in middle school but I know that energy flows from warmer to cooler objects. I will figure this one out! If I don't I am very sorry.

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
