What are the reactions of various metals with water?
Understand the Problem
The question is discussing chemical reactions involving metals and water, particularly how different metals react with water at varying temperatures. It provides equations and explanations related to these reactions.
Answer
Metals form hydroxides and hydrogen gas; reactivity varies.
Metals like potassium and sodium react with water to form metal hydroxides and hydrogen gas, often violently. Calcium reacts less violently. Magnesium needs hot water to react. Aluminum, iron, and zinc react with steam to form oxides and hydrogen.

More Information
The reactivity depends on the metal's position in the periodic table. Alkali metals react vigorously, while transition metals react less readily.
Tips
A common mistake is assuming all metals react with water similarly; however, their reactions depend on specific properties such as position in the reactivity series.
