[2] (8pts) - Use the given properties to identify the type of compound and the state at room temperature. - Use the periodic table to identify the type of elements in each compound and indicate whether the type of compound is consistent with the component elements, or whether it is unexpected. If unexpected, suggest an explanation. (a) Strontium bromide SrBr2 melting point 643C. Conducts electricity when molten. (b) Ethyl acetate CH3COOC2H5 - boiling point 77C. Ethyl acetate is a non-conducting liquid. (c) Sulfur dioxide SO2 - Boiling point 10C. Liquid SO2 does not conduct but forms a conducting acidic solution in water. (d) Manganese(VII) heptoxide Mn2O7 - an explosive red liquid which does not conduct but forms a conducting acidic solution in water
