The metal iridium (lr) crstallizes with a face-centered cubic unit cell. given that the length of the edge of a unit cell is 383 pm, determine the density of iridium in g/cm3.
Complete this equation to show how hydrofluoric acid, HF, acts as a Brønsted-Lowry acid in water. HF+H2O=?
Luminol is so sensitive that it can detect blood that has been diluted 10,000 times. A basic solution of luminol is often sprayed onto surfaces that are suspected of containing minute amounts of blood.
