Explain the density you calculated for the liquid
If your pipet was calibrated incorrectly so it transferred too muchsolution, the density you calculated for the liquid would tend tobe [larger,smaller] than the correct value. Why?

A student spots an unknown sample on a TLC plate and develops it in dichloromethane solvent. Only one spot, for which the Rf value is .95, is observed. Does this indicate that the unknown material is a pure compound?
Determine the specific net-work (i.e. net-work per unit mass flow) in terms of the initial temperature of the cycle. Solve the problem algebraically at first, then sub in values for k, r, r_c, c_p, and c_v.
You and another student were each given an unknown compound. Both samples contained colorless material. You each used the same brand of commercially prepared TLC plate and developed the plates using the same solvent.

If we model the Earth-cloud system as a huge capacitor, what are the capacitance of the Earth-cloud system, the charge stored in the "capacitor", and the energy stored in the "capacitor"?
It is proposed that the new design be implemented only if sample data strongly indicates a reduction in true average braking for the new design. A sampe of 36 observations of the new design resulted in a sample mean of 114.8 ft and a standard devi
