Please help me with my he. Please answer letter a numbers 1-3 completely. Please refer on the text below as well as the picture included. Note: The picture inlcuded is the first page. TYPES OF SOLIDS AND THEIR PROPERTIES Solids can be categorized as crystalline and amorphous. The difference in properties of these two groups of solid arises from the presence or absence of long range order of arrangement of the particles in the solid. Properties Crystalline Solid Amorphous solid Arrangement of particles Arranged in fixed geometric pattern or lattices. Have random orientation of particles Behavior when heated Attractive forces are broken by same amount of energy, thus, becomes liquid at a specific temperature. Softens when gradually heated, they tend to melt over a wide range of temperature. FACTS: More than 90% of naturally occurring and artificially prepared solids are crystalline.

Carbon disulfide has a vapor pressure of 363 torrtorr at 25 ∘C∘C and a normal boiling point of 46.3∘C Find ΔHvap for carbon disulfide. Express your answer to two significant figures with the appropriate units.
Solve correctly please. Should correct. The following information is given for mercury at 1atm: boiling point = 357 °C Hvap(357 °C) = 59.3 kJ/mol melting point = -39 °C Hfus(-39 °C) = 2.33 kJ/mol specific heat solid= 0.141 J/g°C specific heat liquid = 0.139 J/g°C what kJ are required to melt a 41.5 g sample of solid mercury, Hg, at its normal melting point.

Sam knows that he has one of 3 possible liquid unknowns: tetrahyrofuran (bp 65-67°C), ethyl acetate(bp 76-77°C), or toluene (bp 110-111°C). He sets up for a microscale bp determination and clamps thewhole shebang in a water bath. Fifteen minutes late the water is boiling like crazy, but he has yet tosee a single vapor bubble escape from the capillary tube. He double-checks his set-up and everythingis fine so now he’s totally confused. What must his unknown be and why? Break it to him gently…hedoesn’t want to feel like a total idiot.
At about what temperature does the sample change phase? Justify your Answer based on the cooling curve shown above.
A solution of acetic acid CH3COOH and water is boiling at 100.4°C . A sample of the vapor above the solution is cooled until it condenses. This condensed sample is analyzed, and turns out to be 10.% acetic acid by mass. Calculate the percent by mass of acetic acid in the boiling solution. Here's some data you may need: normal boiling point density vapor pressure at 100.4°C acetic acid 118.°C 1.1gmL 538.torr water 100.°C 1.00gmL 771.torr Be sure your answer has 2 significant digits. Note for advanced students: you may assume the solution and vapor above it are ideal.
