Astudent poses the question: how does the presence of dissolved salt affect the freezing point of water? to answer this question, the student set up two conditions. in the first condition, the student added salt to water in a container and referred to this condition as the variable. in the second condition, the student did not add any salt to water in a second container and referred to this condition as the control. the student took both containers and attempted to freeze the water at various temperatures to assess the freezing point. would this be a valid experiment?

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
