Besides its use in making black-and-white film, silver nitrate (agno3) is used similarly in forensic science. the nacl left behind in the sweat of a fingerprint is treated with agno3 solution to form agcl. the precipitate is developed to show the black-and-white fingerprint pattern. given δhlattice of agno3 = 822 kj/mol and δhhydr = −799 kj/mol, calculate its δhsoln.
