Question 14

A marine engineering company is selecting materials for two distinct applications in an offshore platform:

  1. A solid catalyst to accelerate the industrial hydrogenation of organic compounds at high temperatures.
  2. A sacrificial anode to protect a steel structural support (primarily composed of iron) submerged in seawater from corrosion.

Which of the following pairs correctly identifies a suitable metal for each application?

A

Catalyst: Nickel\text{Nickel}Nickel; Sacrificial anode: Zinc\text{Zinc}Zinc

B

Catalyst: Zinc\text{Zinc}Zinc; Sacrificial anode: Copper\text{Copper}Copper

C

Catalyst: Sodium\text{Sodium}Sodium; Sacrificial anode: Magnesium\text{Magnesium}Magnesium

D

Catalyst: Nickel\text{Nickel}Nickel; Sacrificial anode: Copper\text{Copper}Copper
