At what velocity (m/s) must a 15.9 g object be moving in order to possess a kinetic energy of 1.0J?
In solid geometry as three dimensional objects become larger the ratio of volume to surface area increases. Relate this statement to the claim that infants are more vulnerable to radiation damage then adults.
The Ka for lactic acid is 1.4x10^-4. What is the pH of this buffer after .10 mol of solid NaOH has been added?

The vapor pressure of CCl3F at 300 K is 856torr. If 11.5 g of CCl3F is enclosed in a 1.0 -L container will any liquid be present? If so define what is the mass of liquid in grams
A solution was analyzed using AA spec for Au. The signal was 150. This sample solution was placed in a 10 mL container and spiked with 2 mL of a 0.125 mM standard Au solution. The spiked solution returned a signal of 185.
Desalination of brackish water is achieved by evaporation. A fraction of feed water is sent through an evaporator and the other is bypassed. The fraction bypassed and the pure water leaving the evaporator are mixed together to give the desalinasie..
Depict the structural formula for compounds 1 to 5. A certain alcohol C4H10O (1) gives a (+) reaction with chromic acid (2), the alcohol (1) produces a white precipitate (3) within a few minutes of the addition of ZnCl2/HCl.
A chemist must prepare 0.9 L of sodium hydroxide solution with a pH of 13.40 at 25 C. He will do this in three steps: Fill a 0.9 L volumetric flask about halfway with distilled water
Derive ( in Cartesian coordinates) the quantum mechanical operators for the three components of angular momentum starting from the classical definition of angular momentum, l = r × p. Show that any two of the components do not mutually commute, an..
HClO is a weak acid (Ka = 4.0 × 10-8) and so the salt NaClO acts as a weak base.
Can glucosamine be drawn as a linear molecule or does it only exist as a ring structure
