6. A student investigates the properties of an unknown liquid substance in a beaker. The student finds the substance has a mass of 56.2 g and a volume of 42.3 mL. The
liquid has a yellow, translucent appearance. The liquid has a freezing point of 13°C
and a boiling point of 105°C. When the liquid boils, a white powder residue is left in
the beaker.
What conclusion can the student make based on the evidence collected?

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
