Activity A: Volume of liquids
.
Get the Gizmo ready.
Drag all objects to the cabinet.
• Move the 25-ml graduated cylinder, the 250-ml
beaker and the 2-ml pipette to the counter
Introduction: Graduated cylinders are precise tools for measuring volume. Most graduated
cylinders are marked in milliliters. There are 1,000 milliliters in 1 liter (about two cups)
Goal: Fill a graduated cylinder with a given amount of water.
1. Prepare Place the 250-ml beaker below the faucet and fill it with water. (Move the faucet
handle up to pour faster.) You will use the beaker as a source of water in your experiments.

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
