Consider a 2430-lb automobile clocked by law-enforcement radar at a speed of 85.5 mph (miles/hour). If the position of the car is known to within 5.0 feet at the time of the measurement, what is the uncertainty in the velocity of the car?
If the speed limit is 75 mph, could the driver of the car reasonably evade a speeding ticket by invoking the Heisenberg uncertainty principle?

One mole of neon gas equals how many grams? Round to the nearest hundredth. Don't forget the units. Be sure to abbreviate the units.
What amount of the excess reagent remains after the reaction is complete in grams?
If 25.00 mL of 0.07976 M benzoic acid is neutralized by 26.48 mL 0.07530 M NaOH, calculate the quantities of benzoic acid and NaOH you would need to prepare the volume of 1:1 buffer.
What would be the expected CNMR, HNMR, and IR spectra for lidocaine, 2,6-dimethylaniline, and alpha-chloro-2,6-dimethylaniline?
why is the ortho-form of the diamine, and why is the ortho- form of the diamine a hindering impurity that must be rigorously removed before the production of Kevlar and Nomex?
