Question

in the 19th century, the hulls of wooden ships were often lined with muntz metal, a brass alloy composed of approximately 60 mole percent copper and 40 mole percent zinc. in seawater, the alloy would slowly release copper atoms, which repelled sea organisms and prevented them from attaching themselves to the hull of the ship. which of the following diagrams best depicts the structure of muntz metal? choose 1 answer

Explanation:

Muntz metal is a substitutional alloy of copper and zinc. In a substitutional - alloy, atoms of one metal substitute for atoms of another metal in the crystal lattice. The alloy is composed of approximately 60 mole percent copper and 40 mole percent zinc. We need to look for a diagram that shows a random distribution of two types of atoms (representing copper and zinc) where the ratio is roughly consistent with the given mole - percentages.

Answer:

B. (Assuming B shows a random distribution of two types of atoms with a ratio that is approximately 60:40 for the two elements as described in the alloy composition)
