For the answer to the question above, <span>The formula for freezing point depression is </span>
<span>ΔTf = mkfi </span>
<span>kf is the freezing point constant </span>
<span>i is the Van't Hoff factor which in this case is 1 </span>
<span>m is molality (moles of solute/kg of solvent) </span>
<span>ΔTf is temperature change </span>
<span>ΔTf is 2.17 °C, the molality is the amount of solute Quinine </span>
<span>in the solvent cyclohexane. We cannot calculate moles therefore we need to substitute moles with g/mm. </span>
<span>moles = g/mm so molality=(g/mm)/kg </span>
<span>molality = (0.845/mm)/0.025 = 33.8/mm </span>
<span>2.17 = 33.8/mm(20.8) rearrange </span>
<span>mm = (33.8/2.17)(20.8) = 324g/mol</span>
The temoerature decreases because the average kinetic energy is always linearly related to temperature
I think iron because the other options are all bad conductors.
Answer is: continental tropical <span>type of air mass most likely located over Atlanta and Georgia.
</span><span>Atlanta and Georgia have a </span>humid subtropical climate (<span>hot and humid summers, mild winters)</span><span> with four distinct seasons and good precipitation year round.
</span>Gulf of Mexico<span> can bring warm air and there is cold air from Artic.</span>
