Air is made up mostly of O 2 , N 2 , and CO 2 . If the total pressure of air is 765mmHg and P (N2) = 0.79 atm and P (CO2) = 0.05 atm, then what is the partial pressure of the O 2 ?

Sodium nitrite (nano2) reacted with 2−iodooctane to give a mixture of two constitutionally isomeric compounds of molecular formula c8h17no2 in a combined yield of 88%. draw reasonable structures for these two isomers. click the "draw structure" button to launch the drawing utility. place the two compounds in the appropriate boxes below.
