Think about the chain of dominoes as a system. What are the system's inputs and outputs? How is the process started by the tiny domino at the beginning of the chain able to result in the toppling of the giant domino at the end of the chain?

Ahypothetical metal has an orthorhombic unit cell for which the a, b, and c lattice parameters are 0.413 nm, 0.665 nm, and 0.876 nm, respectively. (a) if there are 8 atoms per unit cell and the atomic packing factor is 0.536, determine the atomic radius (in nm). (b) if the density is 3.99 g/cm3, calculate the metal's atomic weight (in g/mol).
