In this video, Michael from Conquer Chemistry explains single replacement reactions, where an ionic compound reacts with an element or a compound made of a single element, resulting in a new ionic compound and an element. He demonstrates this through three examples: zinc oxide with sodium, sodium iodide with bromine, and magnesium with hydrochloric acid. Each example involves assigning charges, using the crisscross method to balance charges, and ensuring the reaction is balanced. The video concludes with a recap and encourages viewers to engage with the content and seek further tutoring if needed.

What is a single replacement reaction?

• A reaction where two ionic compounds exchange ions.
