Answer: Element M is a shiny and highly reactive metal
Chapter 8, Problem 8.8b(choose chapter or problem)
Element M is a shiny and highly reactive metal (melting point 63C), and element X is a highly reactive nonmetal (melting point 27.2C). They react to form a compound with the empirical formula MX, a colorless, brittle white solid that melts at 734C. When dissolved in water or when in the molten state, the substance conducts electricity. When chlorine gas is bubbled through an aqueous solution containing MX, a reddish-brown liquid appears and Cl2 ions are formed. From these observations, identify M and X. (You may need to consult a handbook of chemistry for the meltingpoint values.)
