Question

Which statement is most likely true regarding two aluminum blocks, 1 and 2, that are sitting the same room for weeks. (Block 2 is much bigger than Block 1).

a) Block 1 will oxidize faster than Block 2
b) Block 2 will oxidize faster than Block 1
c) Both blocks will oxidize at the same rate
d) Neither block will oxidize

Answer 1

The correct statement is (b) Block 2 will oxidize faster than Block 1 due to the larger surface area. Aluminum is a reactive metal that readily forms an oxide layer on its surface when exposed to air. The size of the block does not affect the rate of oxidation, but the larger surface area of Block 2.

Step-by-step explanation:

The correct statement is (b) Block 2 will oxidize faster than Block 1. Aluminum is a reactive metal that readily forms an oxide layer on its surface when exposed to air. The size of the block does not affect the rate of oxidation, but the larger surface area of Block 2 will allow for more contact with air, resulting in faster oxidation compared to Block 1.
