Answer:
The difference in temperature is significant means that the lower-boiling liquid finishes distilling at a temperature that is too low for the higher-boiling liquid to be in vapor form yet.
Explanation:
The temperature will rise as the vapor of lower-boiling liquid rushes into the distillation head. However once the lower-boiling liquid is done distilling, there is a temperature drop because while the lower temperature liquid is done distilling, the temperature is still too low for the higher-boiling liquid to be rushing in as a vapour, so the temperature drops.
The estimated number of compounds
formed by the elements in the periodic table is far greater than 118 because
elements can combine in various ways. Compounds are substance composed of more
than one element held together by chemical bonds. Additionally, they can be
converted to a different chemical composition by interaction with another
compound via a chemical reaction.

0.030 mol Na2S2O3
From the balanced equation, the <em>molar ratio</em> of Na2S2O3:Cl2 is 1:4.
∴ Moles of Na2S2O3 = 0.12 mol Cl2 x (1 mol Na2S2O3/4 mol Cl2)
= 0.030 mol Na2S2O3
