Ammonia, nh3, can be made by reacting nitrogen and hydrogen and the equation is n2 + 3h2 --> 2nh3 how many moles of nh3 can be made if 9 moles of h2 react with enough n2? mol

9 moles of H2 means you have a total of 18 moles of H2 (9*2). In NH3, the hydrogen comes in sets of 3 (hence H3 at the end) 18/3=6 therefore you need to have made 6 moles of NH3 to satisfy it, since you have enough N2 this can work so you make 6 moles of NH3

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
