- <u><em>C) How much energy was added to the substance to increase molecule motion? </em></u>
Explanation:
<em>The most relevant question to ask regarding this change</em> must take into account the physical knowledge about matter.
When matter changes from<em> liquid </em>state to <em>gaseous</em> state, a physical change called evaporation, the particles (molecules or atoms) of the <em>pure substance </em>will separate from each other, take up more space and move faster.
<em>Condensation</em> is the opposite to evaporation, thus the option A) is not the most relevant question.
<em>The charge of the particles</em> does not change; so the option B) is not relevant at all.
The particles should gain energy from the surroundings to <em>increase</em> their <em>motion</em> (kinetic energy) when they pass from liquid state, where they move slower, to gas state, where they move faster. Hence, the option<em> C), How much energy was added to the substance to increase molecule motion?</em> , is totally relevant.
Since this is an increase in the <em>kinetic energy of the molecules</em>, the option D) is not relevant.
A. The atmosphere is layered
Answer:
Explanation:
functional groups are specific substituents or atoms within molecules that brings about chemical reactions of those molecules. There is the same or similar chemical reaction in compounds with the same functional groups.
1.)The functional group in Alkyl halides is halogen atom whille
The functional group in Alcohols have
is OH group. There is a double bond in HX or an HOH molecules.
2.)The functional group of carboxylic acid is an organic compound is carboxyl functional group.While The functional group in amine contains a basic nitrogen atom with a lone pair of electrons.
3.)The functional group in ester is a carboxylic acid derivative that is analogous to the Amides
4.) A carboxylic acid has carboxyl functional group. However the hydrogen of the hydroxyl group is can be ionized. In an ester, there is a replacement of hydrogen of acarboxylic acid group by an alkyl group
Answer:
c.O
Explanation:
From the periodic table:
Ionization energy tends to increase from IE6 → IE7 drastically at 13329 to 71345. Hence, from this process, we can infer that the removal of electrons takes place from the inner shell which in turn has a higher affinity for the nucleus. This must be oxygen because oxygen contains 6 valence electrons. The removal of this valence electron after the sixth ionization results in the achievement of a stable nearest Noble gas configuration. Hence, the rapid change in the ionization is obvious from IE6 to IE7.
Thus, the element that relates to the IE trend is oxygen.
