Reactions with Bases and Displacement Reactions

The video tutorial explores the safety of train travel and the maintenance of railway tracks, focusing on the thermite reaction used to repair cracks. It explains metal reactivity and displacement reactions, using examples like iron displacing copper. The tutorial also covers how alkalis react with metals, particularly aluminum, and briefly touches on non-metals' reactions with bases.

Why can't copper displace iron in a chemical reaction?

What is a metal displacement reaction?

How does aluminum react with alkali, and what are the products formed?
