Questions from Embibe Experts Solutions for Exercise 1: Exercise 1 with Hints & Solutions
On the basis of reactivity of different metals with oxygen, water and acids as well as displacement reactions, the metals have been arranged in the decreasing order of their reactivity. This arrangement is known as activity series of metals.
The basis of reactivity is the tendency of metals to lose electrons. If a metal can lose electrons easily to form positive ions, it will react readily with other substances. Therefore, it will be a reactive metal. On the other hand, if a meal loses electrons less rapidly to form a positive ion, it will react slowly with other substances. Therefore, such a metal will be less reactive.
Which of the following represents the correct order of reactivity for the given metals?
The following question consists of two statements-Assertion and Reason. Answer this question by selecting the appropriate option given below:
Assertion: Iron is found in the free state in nature.
Reason: Iron is a highly reactive element.
Metal oxides that are soluble in water dissolve in them to further form metal _____.
