Standard addition: Lithium in the blood serum of a manic-depressive patient treated with lithium carbonate is determined by flame emission spectrophotometry using a standard additions calibration. One hundred microliters of serum diluted to 1mL gives an emission signal of 6.7 cm on the recorder chart. A similar solution to which 10 microliters of a 0.010 M solution of LiNO3 has been added gives a signal of 14.6 cm. Assuming linearity between the emission signal and the lithium concentration, what is the concentration of lithium in serum, in parts per million?
A flask is filled with vapor by boiling a volatile unknown liquid in the flask. As it boils away, the vapor of the unknown pushes the air out of the flask through a tiny pinhole opening and eventually the flask is filled with an atmosphere compose..
The bottom liquid is a relatively heavy lubricating oil, and the top liquid is water. Of the total block volume, 54.2% is immersed in the oil and the balance is in the water. In a separate experiment, an empty flask is weighed, 35.3 cm cubed of th..

Describe how a phospholipid differs from other fatty acids. How does this difference allow the formation of a bilayer in an aqueous medium
H2S and H2O have similar structures and their cenertal atoms belong to the same group. Yet H2S is a gas at room temperature and H2O is a liquid. Use bonding principles to explain why this is.
