what are the classifications? ionic, macromolecular, etc? a melting point < 100 °C, was soluble in both water and polar organic solvent but insoluble in non polar organic solvent. It conducted electricity in water solution and in molten but not in a solid form. a melting point > 500°C, was soluble in water and slightly soluble in polar organic but insoluble in non polar organic solvent. It conducted electricity in water solution as well as molten but did not conduct...

1. You are given a quantity of a volatile liquid substance and asked to determine its molecular weight. To do that, you place a sample of the liquid in a 200.0-mL flask and submerge the flask in a boiling water to vaporize all of the liquid. The vapor fills the flask and the excess escapes,. Now you cool the flask so that all the vapor in it condenses, and you weigh the flask and liquid. After you subtract the mass...

In the lab you are given 4 bottles, each containing about 5 grams of finely powdered white substance. Located near the bottles are four lables which indicate that each bottle contains a high purity substance. One bottle contains glucose ( C6H12O6) another bottle sodium chloride (NaCl), another aluminum oxide (Al2O3), and another zinc sulfate (ZnSO4). Assume that these labels belong to the bottles and that each bottle conatins a single substance. Describe the tests that you could conduct to determine...

Given an unknown sample that could contain Cr3+, Mn2+, and/or Fe2+ you strip the metal ions from pieces of chalk using hydrochloric acid, subsequently concentrating the solutions and adding sodium hydroxide. You then add sodium hypochlorite and ammonium hydroxide. After boiling and centrifuging the product, you isolate the solution by decantation. You wash the remaining solid twice with water and sodium hydroxide. Then, water and sulfuric acid are added to this solid. The decanted solution is yellow and you decide...

1. The observations of the vitamin solution reactivity for the ions tests were given without taking into account the initial appearance of the vitamin solution. Recalling your observations of the vitamin solution appearance after its preparation (in A), how do you think its initial appearance would have change the observations when a white precipitate was observed? 2. For the test to detect the ammonium NH4+ ions using NaOH, a gas is produced. a. What is the name and formula of...

You are given 100 g of coffee (same specific heat as water) at 80.0° C (too hot to drink). In order to cool the coffee to 50.0° C (neglect heat content of the cup and heat exchanges with the surroundings) calculate: a. How much tap water at 20.0° C must be added? b. How much ice (at 0.0° C) must be added? c. How much ice (at -10.0° C) must be added? 2. How much energy is required to heat...
