Reactions of Metals with Oxygen, Acids and Water

The video tutorial covers the reactions of metals with oxygen, acids, and water. It explains how metals form metal oxides with oxygen, metal salts and hydrogen gas with acids, and metal hydroxides with water. The tutorial highlights exceptions, such as copper's lack of reactivity with acids and water. It concludes with a discussion on how metals form positive ions during these reactions.
