Two white crystalline samples need to be identified. As a first step the type of solid is identified. The first powder has a noticeable odor, a melting point of about 80°C, and is insoluble in water and soluble in hexane. The second dissolves easily in water producing an electrolyte solution and has a melting point of about 1500°C. What are the types of the first and second samples? O First is molecular, second is ionic O First is ionic, second is metallic O First is molecular, second is covalent network O First is metallic, second is covalent network
