Answer:

1. Incorrect, it occurs in gases as well or generally in fluids.

2. Correct.

3. Incorrect.

Explanation:

Hello,

1. Convection, is a heat transport phenomena which occurs when a fluid transfers energy in the form of heat to a surface or vice-versa, in such a way, it occurs fluid, say, in both gases and liquids.

2. In this case, radiation is a heat transfer phenomena which occurs by thermal waves transferring the heat; such waves are generated by a hot body which it is said to irradiate the waves by cause of its inner temperature, therefore, as it could be surrounded by a colder space, heat is transferred. As a result of the high temperature, all substances could radiate heat.

3. In this case, it is widely known that normal temperature is between 20 and 25 ºC while the body's inner temperature is about 37 ºC for our organism to work properly. In such a way, those temperatures are different.

Best regards.

Place the following substances in order of decreasing vapor pressure at a given temperature: BeF2, CH3OH, OF2?
Anit [1.1K]

Answer:

(b) BeF2 > OF2 > CH3OH

Explanation:

The degree and type of intermolecular forces present in a substance influences its vapour pressure considerably. The greater the magnitude and strength of intermolecular forces in the substance, the lower the vapour pressure of the substance.

BeF2 molecules are held together by weak vanderwaals forces hence BeF2 will exhibit the least degree of intermolecular interaction and have the highest vapour pressure. OF2 molecules are bound together by dipole interactions hence it will exhibit a lower vapour pressure compared to BeF2. CH3OH molecules form hydrogen bonds with water molecules hence it will exhibit the least vapour pressure among the trio.

Draw the structure corresponding to the followingname:_________.
natita [175]

Answer:

See figures 1 and 2

Explanation:

For this question, we can analyze each compound:

<u>a. (4Z,3S)-2,4,7-trimethyl-3-amino-4-octene</u>

<u />

In this case, we have to start with a <u>carbon chain of 8 carbons</u>. Then in carbons 2, 4 and, 7, we have to put three methyl groups (CH_3). In carbon 4 we have to put an amino group (NH_2). When we put the amino group in carbon 4 we will have a <u>chiral carbon</u>. So, we have to indicate the orientation in the bond of the amino group. If we want an "S" configuration the atoms must have a <u>counterclockwise orientation</u>. So, the amino group must have a dashed bond. Finally, in carbon 4 we have to put a double bond, the configuration of this double bond is <u>"Z"</u>. So, the most important groups must be on the <u>same side</u>, in this case.

See figure 1 for further explanations

<u />

<u>b. (3S,6R)-6-(2,4-dinitrophenyl)-3-amino-1-heptyne</u>

<u />

In this case, we have to start with a <u>chain of 7 carbons</u>. In carbon 3 we have to put an amino group (NH_2). When we put this group in carbons we will have a chiral carbon is the name we have an <u>"S" configuration</u> for this carbon. So, we have to use the dashed bond in order to have a <u>counterclockwise orientation</u> for all the atoms bonded on carbon 3. In carbon 6 we have to put a big group "2,4-dinitrophenyl". In this group, we have a bond with the main carbon chain in carbon 6 (of benzene), in this same benzene ring we have to put nitro groups (NH_2) in carbons 2 and 4. Additionally, carbon 6 is a chiral carbon, and the configuration of this carbon is "R". Therefore we have to use a wedge bond for all the "2,4-dinitrophenyl" in order to have a clockwise orientation for all the atoms bonded on carbon 6. Finally, we have to put a triple bond between carbons 2 and 3.

See figure 2 to further explanations
