Chapter 7, Problem 51E

Interpretation Introduction

Interpretation:

The correct option corresponding to the metals which react with water at room temperature are to be identified.

Concept Introduction:

Some metals are so reactive that they can react directly with water at room temperature. These metals are called active metals. These active metals react with water and form their hydroxide along with the evolution of hydrogen gas. The relative order of most common active metals arranged by their ability to undergo reaction in water is shown below.
