Input: Consider Input: Question: The SO2 molecule is:
Options: <0> Linear, with the S atom in the center. <1> Linear, with one of the atoms of O in the center. <2> Angular, with the S atom in the center and with an angle close to 120 (equilateral triangle) and a free pair of electrons. <3> Angular, with one of the atoms of O in the center and with an angle of approximately 120 (equilateral triangle) and a pair of free electrons. <4> Angular, with the S atom in the center and with an angle close to 109 (tetrahedron) and two pairs of free electrons.

Output: chemistry

Input: Consider Input: Question: In chromatography, the dead time can be defined as:
Options: <0> The time between the injection of a sample and the appearance of a solute peak in the detector. <1> The factor that indicates the amount of time a solute spends in the stationary phase in relation to the time spent in the mobile phase. <2> The time it takes for a non-retained species to pass through a chromatographic column. <3> The time it takes for the analyte to pass through the chromatographic detector. <4> The relationship between the average linear velocity and the packing length of the column.
Output: chemistry
