Calculate the energy for vacancy formation in nickel (Ni), given that the equilibrium number of vacancies at 850C (1123 K) is 4.7 1022 m3 . The atomic weight and density (at 850C) for Ni are, respectively, 58.69 g/mol and 8.80 g/cm3 .

Suppose that during that icy hot lab 65,000 j of energy were transferred to 450 g of water at 20°c what would have have been the final temperature of the water

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.
