B. no
Pumice is a light, porous volcanic rock that typically floats in water and has a streak of white. The fact that this sample sinks in water and has no streak suggests that it is not pumice.
Exhibit 6: Pumice
You do the following tests and find
these results:
Streak: none
Magnetic:no
Float/Sink: sinks
Mass: 13.7 g
Reaction to HCL: no reaction

what is it
Given the characteristics provided (sinks in water, no streak, no reaction to HCL), the material does not match the properties of pumice. It is difficult to determine the exact identification without further testing or information. It could potentially be a different type of volcanic rock, but additional analysis would be needed for a definitive identification.
