Dr. bunsen has a problem—he stored a rack of six bottles filled with clear colorless liquids too close to a heat vent and the labels fell off of each of the bottles. he needs your in order to correctly identify each of the solutions. below is a list of the solutions:  pure di water  0.10 m agno3  0.20 m hcl  0.20 m hno3  0.20 m koh  0.50 m nahco3 we are provided with ph paper and phenolphthalein

What!  Your teacher is crazy - half of those things will catch on fire if they are mixed!  You should double check to make sure you have them written down right or you could really get hurt!

If you mix HNO3 and HCl you will get a brown gas (don't light it or smell it!).  The one that is heavier is the HNO3, because it has more atoms in it.  Then, mix the silver one (AgNO3) with KOH - it will give a silver coating to the plastic (search for Tollins Test to see what it looks like).  DI water will absorb CO2 from the air and make carbonic acid, so the one that is acidic will be the water.

Good luck!

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
