Below are listed diffraction angles for the first three peaks (first-order) of the xray diffraction pattern for some metal. Monochromatic x-radiation having a wavelength of 0.1254 nm was used. i. Determine whether this metal's crystal structure is FCC, BCC, or neither FCC or BCC and explain the reason for your choice. ii. If the crystal structure is either BCC or FCC, determine the atomic radius of the metal. Peak Number Diffraction Angle (2 q) 1 31.2° 2 44.6° 3 55.4°

The concept of empiricism states that all rationally accepted knowledge is determined from experience. francis bacon was one of the first scientists to promote this theory. what was it’s impact on society?

Mrs. smith ordered a root beer float (vanilla ice cream + root beer). mrs. smith noticed that the three states of matter (solid, liquid, and gas) all existed simultaneously in her root beer float. a. identify each phase of matter in the root beer float. b. describe the particles of all three phases of matter in the root beer float. (how are the particles arranged and moving? ) c. identify one phase change you would see in a root beer float and described what causes this change.
