How many calories are required to increase the temperature of 13 g of ethanol from 11 °c to 23 °c? the specific heat of ethanol is 0.59 cal/g °c?

The  number  of calories  that are required to increase  the temperature of 13 g of ethanol  from 11c to 23 c is =92.04 Cal

     calculation

 This is calculated Q(heat)= MCΔT   formula  where
Q(heat)=?
M(mass)= 13g
C(specific heat capacity)=0.59 cal/g/c
Δ T(change in temperature)=23-11= 12 c

Q  is therefore = 13g x 0.59 cal/g/c  x12 c= 92.04 Cal

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 

The answer is nitrogen-containing bases
