A 1.000-g sample of XI2 is dissolved in water, and excess silver nitrate is added to precipitate all of the iodide as AgI. The mass of the dry AgI is found to be 1.375 g. Calculate the atomic weight (mass) of X.
- Light: - The light we can see is visible light, and is just one type of electromagnetic (EM) radiation - There are many different types of EM radiation - Example: - Yellow light has a wavelength of 589 nm. What is the frequency of this radiation - C = 3 x 10 m/s -9 -7 - 589 nm x x 10 m / 1 nm = 0 m - (3 x 10 m/s) / (5.89 10
