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.

The heating curve shows the energy gain of a substance as it changes from solid to gas. Which section of the graph shows the liq

Schach [20]

Answer:

C. C

Explanation:

The heating curve is a graphical representation shows that how different phases of substances change as it is influenced by the increase in temperature or heat.

Section A represents solid phase, Section B represents solid-liquid phase, section C represents liquid phase, section D represent liquid-gas phase and section E represents gas phase.

Section C of the graph shows the liquid phase of the substance gaining kinetic energy. During Phase C, heat energy is absorbed and liquid particles gain kinetic energy to change into gas form that is section E.

Hence, the correct option is C.C.

Answer:

37.85 liters

Explanation:

they need 10 gallons for a month (2.5*4)

after that, convert gallons to liters (conversion to liters= 3.785)

10*3.7585= 37.85
