Question

This passage describes a chemical reaction. Read the passage. Then, answer the question below.

Over 200,000 miles of train tracks have been built in the United States since the early 1800s. Workers who build new train tracks often use a process called thermite welding to connect short pieces of metal track. This type of welding uses thermite powder, which is a mixture of aluminum metal (Al) and ferric oxide (Fe2O3). A worker places the powder between two pieces of track and burns it to form aluminum oxide (Al2O3) and iron metal (Fe). This process releases an enormous amount of energy that melts the two pieces of track together.

In the chemical reaction described in the passage, which of the following are products? Select all that apply.

ferric oxide (Fe₂O3) 
iron (Fe) 
aluminum (Al) 
aluminum oxide (Al₂O3)
