A column for gas chromatography features: length of packing 52 cm; volume flow rate 0.421 mL/min, volume of the analyte in the mobile phase (VM) 1.57 mL, and volume of the analyte in the stationary phase (VS) 0.321 mL. A chromatogram of a mixture of species A, B, C, and D provided the following data:

Most ionic compouds are crystalline solids at room temperature. true falseionic compounds are electrically neutral. true falseionic compounds generally have low melting points. true falsewhen melted, ionic compounds do not conduct electricity. true falsethe electrostatic attraction between an anion and a cation is an ionic bond. true false
