Draw the structural formula of trans-1,3-dimethylcyclohexane in the chair conformation. choose a chair from the templates toolbar at the bottom. make sure it’s the appropriate chair, including any heteroatoms. replace the appropriate hydrogens with the appropriate ch3 or other groups. important: never delete the hydrogen atoms or bonds in the ring or directly attached to the ring. also, do not try to move them by drag and drop. these actions will break the chair conformation structures. just replace them!

Look picture

Explanation:

The structural formula of a chemical compound is a graphic representation of the molecular structure, showing how the atoms are possibly arranged in space.

The real structure in what cyclohexane exist is called the chair conformation. This conformation is called the chair because it looks  like a reclining lounge chair (Look picture).

The draw of  trans-1,3-dimethylcyclohexane is in the chair conformation. The trans position means that one methyl group is in ecuatorial position while the other one is in axial position.

nacl is added to the aqueous of what? ? in order to get a proper answer you have to specify the exact composition of the aqueous solution.

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
