For every disubstituted cyclohexane, we can draw a Haworth projection and two chair conformations. This is true for all disubsti

tuted cyclohexanes, including cis-1,3-dimethylcyclohexane and trans-1,3-dimethylcyclohexane.
True or False?

Answer:

True.

Explanation:

Both Haworth and chair conformations can be used to represent disubstituted cyclohexanes. However, <u>the energies for each chair conformation are different</u>, thus one conformation will be more favored than the other.

For the 1,3-cyclohexanes, the most stable conformation of the <em>cis</em> isomer has both methyl groups in equatorial positions. Any conformation of the <em>trans</em> isomer puts a methyl group in an axial position. Therefore, the <em>trans</em> isomer has more energy than the <em>cis</em> isomer. We need to remember, though, that <em>cis </em>and <em>trans</em> isomers can’t be interconverted and there is no equilibrium between these.

By weight atmospheric air is approximately 23.15% oxygen and 76.85% nitrogen. What is the partial pressure of oxygen in the air
inna [77]

Answer:

Partial pressure of oxygen = 23.38 kpa (Approx)

Explanation:

Given:

Amount of oxygen = 23.15%

Amount of nitrogen = 76.85%

Pressure (missing) = 101 kpa

Find:

Partial pressure of oxygen

Computation:

Partial pressure of oxygen = [Amount of oxygen x Pressure]/100

Partial pressure of oxygen = [23.15% x 101]/100

Partial pressure of oxygen = 23.38 kpa (Approx)

Kernels of corn are heated and become popcorn. Why is this a chemical change?
goldfiish [28.3K]

Answer:

When popcorn is popped, liquid inside the kernel is changed to steam. Pressure from the steam builds up inside the kernel. When the pressure reached a critical stage the kernel pops turning itself inside out. This is a physical change.
