Hexane (C6H14, density = 0.766 g/cm3), perfluoro-hexane (C6F14, density = 1.669 g/cm3), and water are immiscible liquids; that is, they do not dissolve in one another. You place 10 mL of each in a graduated cylinder, along with pieces of high-density polyethylene (HDPE, density = 0.97 g/cm3), polyvinyl chloride(PVC, density = 1.36 g/cm3), and Teflon (density = 2.3 g/cm3). None of these common plastics dissolves in these liquids. Describe what you expect to see.
Which part of the description of a compound or element refers to its physical properties and which to its chemical properties? (a) Calcium carbonate is a white solid with a density of 2.71 g/cm3. It reacts readily with an acid to produce gaseous carbon dioxide. (b) Gray, powdered zinc metal reacts with purple iodine to give a white compound
Suppose the metallic paper clips (which contain iron) had been replaced by magnesium or nickel. Would using a magnet as a method of separation have worked?
Asbestos is a fibrous silicate mineral with remarkably hightensile strength. But it is no longer used because airborne as-bestos particles can cause lung cancer. Grunerite, a type of as-bestos, has a tensile strength of 3.5x10^2kg/mm²(thus, a strandof grunerite with a 1-mm2cross-sectional area can hold up to 3.5x10²kg). The tensile strengths of aluminum and Steel No.5137 are 2.5104lb/in²and 5.0104lb/in², respectively. Cal-culate the cross-sectional area (in mm²) of wires of aluminumand of Steel No. 5137 that have the same tensile strength as afiber of grunerite with a cross-sectional area of 1.0μ m²

To identify a metal, an experimenter placed, 4850cg sample in a graduated cylinder. He then poured 35.75 mL of water, covering the metal and bringing the liquid level in the cylinder to 42.5 mL. What is the density of the metal in kg/m3?
rosity is a measure of the void or empty spaces in a material and is a fraction of the volume of voids over the total volume. The density of the solid material used to create 7 pieces of 0.97 cm diameter and 1.14 cm height cylindrical beads is determined to be 1.63 g/mL. These beads were then placed in a flask and was filled to the 40 mL mark with a salt solution. The total weight measured of the beads and the salt solution was 46.86 g. Upon further inspection, it was found that manufacturing defects caused the measured porosity of the beads to be at 32%. Assuming that the solution was able to fully fill the empty spaces inside the beads, calculate the density of the salt solution. Show your solutions in the next item Round your answer to 2 decimal places.
