Cory wants to do an experiment to confirm that matter is conserved during a chemical reaction. He decides to use the reaction of baking soda and vinegar. When added together, the two substances foam and bubble. Cory gathers the following equipment: a scale to measure masses a large flask in which to mix the vinegar and baking soda vinegar baking soda a lab book and pen What does Cory still need in order to do his experiment? A. a hot plate B. a way to measure the volume of liquids C. a way to calculate how much baking soda to use D. a way to capture and measure gas

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
