The correct IUPAC name for the following molecule is: _________
andrew-mc [135]

Answer:

A.) trans-2,3-dichloro-5-methyl-2-hexene

Explanation:

The proposed question and structure has been attached to this answer.

The<em> cis</em>- and <em>trans</em>- isomers are used to denote the alignment of the functional groups to the carbon chain side. From the diagram, we see that:

  • the two chloro groups on the main compound are in opposite directions (-<em>trans</em>), and not the same sides (-<em>cis</em>)
  • The bottom extended methyl group is on the 5th carbon as we count from left to right
  • there's a total of 6 carbon atoms with 1 double bond on the second to third carbon.

Hence the name <u>trans-2,3-dichloro-5-methyl-2-hexene</u>

DUE TONIGHT!
GuDViN [60]

Answer:

27J/Kmol

Explanation:

Heat = number of moles times the Moeller heat capacity chimes the change in temperature.

^ Q = nC△T

^ C = Q/ n△T = +53J / (1mol) (299.5K - 297.5K)

^ = 26.5 (rounded to 27)

What controls the volumes of water in each cylinder once equilibrium is established?
Neporo4naja [7]

The increase in volume shift the equilibrium towards making more moles of gas, decrease in volume shift the equilibrium towards producing fewer moles of gas.

<h3>What is equilibrium?</h3>

The equilibrium of the gas is based on the pressure of the gas. With the increase in pressure, the equilibrium moves towards making fewer molecules of gas.

The gas equilibrium is proportional to the equilibrium K.

Increase in volume shift the equilibrium towards making more moles of gas, decrease in volume shift the equilibrium towards producing fewer moles of gas.
