The daily dose of ampicillin for the treatment of an ear infection is 115 mg/kg of body weight. What is the daily dose for a 34-lb child?
Why is it important to the place the thermometer bulb at in the lower part of the Hickman still head? What will happen if you place it either a)too low
The pH at 25 °C of an aqueous solution of the sodium salt of p-cresol (NaC7H7O) is 11.60. Calculate the concentration of C7H7O- in this solution, in moles per liter. Ka for HC7H7O is equal to 6.7E-11.
Compound J, C16H16Br2, is optically active. On treatment with strong base, compounds K and L (each C16H14) are formed; K and L each absorb only 2 equivalents of hydrogen when reduced over a Pd/C catalyst. Compound K reacts with ozone to give pheny..
Car manufacturers are developing engines that use H2 as fuel. In locations where hydroelectric plants produce inexpensive electric power, the H2 can be made industrially by the electrolysis of water.
benzoic acid and dissolve it in 1ml of diethyl ether. this is then extracted with 1 ml of water. the ether is removed, dried with sodium sulfate and ether evaporated yielding 30 mg of benzoic acid. what is the kp value for the ether water system.
