You are a forensic investigator The data for a crime scene is in the following chart Soluble in water Soluble in oil Crime scene Yes powder No Conducts electricity when dissolved in water Yes Melting point high Which statement bests constructs an argument to identify the crime scene powder as one of the following KCI C10Hg C6H O6 The crime scene powder is C 0Hg because it conducts electricity has a high melting point and is soluble in water The crime scene powder is C10H8 or C6H O6 because both of these are soluble in water insoluble in oil conduct electricity and have high melting points The crime scene powder is KCI because it is the only ionic compound choice because KCI contains a metal and a nonmetal and the other 2 compounds do not contain a metal Only ionic compounds conduct electricity when dissolved in water so KCI is the crime scene powder The crime scene powder is C 0H8 or C6H O6 because both of these are covalent compounds because they don t contain a metal They are soluble in water and not oil because they are polar covalent Thus the crime scene powder is one of these two compounds
