Use the CRC Handbook of Chemistry and Physics to look up the density of each of the liquids you will use in this lab and record them in table 13.6 on the data sheet, page 437

It is possible to balance a paper clip on the surface of water in a beaker. lf you add a bit of soap to the water, however, the paper clip sinks. Explain how the paper clip can float and why it sinks when soap is added.

Infer Dehydration occurs when more fluid is lost from the body than is taken in. Scuba divers are advised to hydrate their bodies before diving. Use your knowledge of the relationship between pressure and gas solubility to explain the importance of hydration prior to a dive.

A student dissolves 27.2g of aniline, C6H5NH2, in 1.20102g of water. At what temperatures will the solution freeze and boil? Aniline is used in the polyurethane manufacturing process. Materials made from polyurethane include foams as pictured, spandex, hardwood floor coatings, dolly wheels, and many other end products.

Cooking A cook prepares a solution for boiling by adding12.5 g of NaCl to a pot holding 0.750 L of water. Atwhat temperature should the solution in the pot boil?Use Table 14.5 for needed data.

Can a gas be dissolved in a solid to make a solution? Choose the BEST answwer. a. Yes, we used hydrated copper sulfate in Chem 113 lab, and that was a solution of water in copper sulfate, a solid. Ob. No. Solids cannot act as solvents for gases, their intermolecular forces are too dissimilari. Oc. Oc. Yes, gases can fill the voids between the closely packed particles in a solid, and form a solution. Od. No, gases evaporate too easily and will not stay in a solid.

Miscible liquids from homogeneous mixture when added together. is Toluene miscible with water or miscible With ethyl alcohol? Please i need a clear and simple answer to this question. Thanks

Please don't provide handwritten solution .....

Diffusion will occur when a solute in high concentration migrates to an area of low concentration until the solute is evenly distributed throughout the solution. True or False?

A certain liquid x has a normal boiling point of 119.60 °C and a boiling point elevation constant K,= 1.05 °C•kg•mol. Calculate the boiling point of a solution made of 252.g of barium hydroxide (Ba(OH),) dissolved in 750. g of x. Round you answer to 5 significant digits.
