Answer:
Compound B is ionic. The electronegativity difference is 2.2, which can be determined by subtracting the electronegativity of Element Y from that of Element Z. Electronegativity differences greater than 1.7 indicate ionic bonds.
Hope that helps.
The answer for the following answer is explained below.
The answer is NH_{4} ^{+}
Explanation:
Bronsted-Lowry acid :
It is a solution that donates protons, and is known as a proton donor.It donates protons in the form of hydrogen ion(
).This is reinforced by the definition of an acid ,which is a solution that has hydrogen ions.
In Bronsted-Lowry aci it must contain a hydrogen io that it can give up.When the acid gives a hydrogen ion,the charge of an acid decreases.
Here,
NH_{4} ^{+} loses one hydrogen ion and forms ammonia molecule.
So therefore the Bronsted-Lowry acid is NH_{4} ^{+}.
Answer:
Part A. The solubility of gases in water increases with increasing temperature.
Part B. Hexane (C₆H₁₄)
Explanation:
Part A
<em>Considering factors that affect that solubility which statement below true?
</em>
- <em>With a few exceptions, the solubility of most solid solutes in water decreases as the solution temperature increases.</em> FALSE. With a few exceptions, the solubility of most solid solutes in water increases as the solution temperature increases.
- <em>The solubility of gases in water increases with increasing temperature. </em>
FALSE. In general, the solubility of gases decreases with increasing temperature.
- <em>The solubility of a gas in any solvent is increased as the partial pressure of the gas above the solvent Increases.
</em> TRUE. According to Henry's law, the solubility of a gas in a liquid is proportional to its partial pressure.
- <em>Substances with similar intermolecular attractive forces tend to be insoluble in one another.</em> FALSE. Substances with similar intermolecular attractive forces tend to be soluble in one another.
Part B
<em>
Which of these is the best solvent for nonpolar solutes?
</em>
<em>acetone (CH₃COCH₃)
</em>
<em>ethanol (CH₃CH₂OH)
</em>
<em>hexane (C₆H₁₄)
</em>
<em>water</em>
There is a general rule that states "like dissolves like", meaning polar is soluble in polar and nonpolar is soluble in nonpolar. Thus, hexane, which is the least polar solvent, would be the best choice for nonpolar solutes.
