What is the change in energy of a gas at a pressure of 105 kPa, if 245 J of energy is added causing a change in volume from 25.3
Ahat [919]

Answer:

-1151.5 J

Explanation:

Given that:

The supplies energy = 245 L

The energy used in the expansion of gas = Pressure ×ΔV (change in volume)

At standard conditions;

Pressure = 105 × 10³ Pa

energy used in the expansion = 105 × 10³ Pa × (38.6 - 25.3)L

= 1396.5 J

Thus, the change in the energy of gas = 245 - 1396.5 J

= -1151.5 J

Hence, we can conclude that the gas has lost its own energy in the process of expansion.

Draw the structure of the bromohydrin formed when (Z)-3-hexene reacts with Br2/H2O. Use the wedge/hash bond tools to indicate st
Ipatiy [6.2K]

Answer:

(3R,4R)-4-bromohexan-3-ol

Explanation:

In this case, we have  reaction called <u>halohydrin formation</u>. This is a <u>markovnikov reaction</u> with <u>anti configuration</u>. Therefore the halogen in this case "Br" and the "OH" must have <u>different configurations</u>. Additionally, in this molecule both carbons have the <u>same substitution</u>, so the "OH" can go in any carbon.

Finally, in the product we will have <u>chiral carbons</u>, so we have to find the absolute configuration for each carbon. On carbon 3 we will have an "R" configuration on carbon 4 we will have also an "R" configuration. (See figure 1)

I hope it helps!
