The dissolution of ammonium nitrate, nh4no3, in water is an endothermic process. since the calorimeter is not a perfect insulator, will the enthalpy of solution for ammonium nitrate be reported as too high or too low if this heat change is ignored? explain

 

Explanation:  As already mentioned that the dissolution of ammonium nitrate in water is an endothermic process, which explains that more energy would be needed to break the bond between the reactants rather than the formation of the products.  

Hence, the enthalpy of the solution for ammonium nitrate would be positive in nature as energy is being given to the reactants molecules to get converted into the products.

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
