Which of the following would be considered a solution?

1 answer:

6 0

A solution must have both a solute and a solvent, and they must exist in solution together. the solute must be dissolved in the solvent; salt does not dissolve in a sugar bowl, nor does oil dissolve in water; it is a non polar molecule. we know that sugar (the solute) when added to water(solvent) will dissolve, creating a solution.
therefore, B

Rank the species CH2NH, CH3I, HF, C2H6 from most to least miscible in ammonia (NH3) 1. CH3I > C2H6 > HF > CH2NH 2. CH2N

777dan777 [17]

Answer:

$HF>CH_{2}NH>CH_{3}I>C_{2}H_{6}$

Explanation:

$NH_{3}$ is an weak base. HF is an weak acid. Hence an acid-base reaction will ocuur between $NH_{3}$ and HF resulting a homogeneous mixture.

$NH_{3}$ is a polar protic molecule. Hence it can form hydrogen bonding with another polar protic molecule $CH_{2}NH$ . Also dipole-dipole attraction force along with london dispersion force exists between $CH_{2}NH$ and $NH_{3}$ .

$CH_{3}I$ is a polar molecule. Hence only dipole-dipole attraction force along with london dispersion force operates between $CH_{3}I$ and $NH_{3}$ .

$C_{2}H_{6}$ is a non-polar molecule. Hence only london dispersion force exists between $C_{2}H_{6}$ and $NH_{3}$ .

So, order of miscibility: $HF>CH_{2}NH>CH_{3}I>C_{2}H_{6}$

E. Give evidence to support or dispute: "In nature, the chance of finding one isotope

Nadusha1986 [10]

Answer:

This question appears incomplete

Explanation:

However, the chance of finding one isotope of an element is not the same for all elements because some elements/isotopes are more in abundance than some other elements/isotopes; for example the most abundant element on earth is nitrogen-14, hence the chances of finding nitrogen-14 in nature is higher the chances of finding any isotope of Xenon.

Also, while isotopes occur naturally, some do not. Hence, the chances of finding a naturally occurring isotopes (no matter how rare like Xenon-126) is higher than the chances of finding artificial radioisotopes like technetium-95 and promethium-146 (whose chances are zero because they cannot be found naturally occurring).
