Question

-10 points SerPSE10 1.1.OP002. An artist creates a solid sculpture made from 8.20 kg of copper. She wishes to creat silver. What is the mass (in kg) of the silver sculpture? (The density of e an identical sculpture, using the same mold used to make the original, out of solid copper is 8.96 x 103 kg/m2, and that of silver is 10.50 x 10° kg/m2) kg Need Help? Read it 10 1.2.P007 A crystalline solid consists of atoms stacked up in a repeating lattice structure. Consider a crystal as shown in Figure a. The atoms reside at the corners of cubes of side L 0.200 nm. One piece of evidence for the regular arrangement of atoms comes from the flat surfaces along which a crystal separates, or cleaves, when it is broken. Suppose this crystal cleaves along a face diagonal, as shown in Figure b. Calculate the spacing d between two adjacent atomic planes that separate when the crystal cleaves nm 27 PM
