Question

Name All of the common noble gases are monatomic and low-boiling. Their boiling points in℃are: Ne--245; Ar--186. Kr--152, Xe--107. Using the periodic table, what can you conclude about the boiling point of Rn from these data? 1. 2. Substances A, B, and C can all act as oxidizing agents. In solution, A is green, B is yellow, and C is red. In the reactions in which they participate, they are reduced to A B and C-ions, all of which are colorless. When a solution of A is mixed with one containing C ions, the color changes from green to red Which species is oxidized? Which species is the oxidizing sgear? When a solution of A is mixed with one containing B-ions, the color remains green. Is A a better oxidizing agent than B? Is A a better oxidizing agent than C? Arrange A, B, and C'in order of decreasing strengths as oxidizing agents. (contiued of following page) 38 EXPERIMENT 3 Alkaline Earths and Halogens You are given an unknown, colorless solution that contains only one of the ions, AT 3. B or C. whose properties are given in question 2. Given the availability of solutions of A. B, and C, develop a simple procedure for identifying the ion that is present in your unknown
