Answer to Problem 1TAI
Arrangements of atoms represent the structural formula of a compound. Thus rearrangements of atoms can result new products with different properties.
Explanation of Solution
In combination reactions two or more than two molecules react to produce a single product in which rearrangements of atoms take place.
Similarly in decomposition reactions one molecule is broken down to two or more than two new molecules. Even here, rearrangerments of atoms take place.
Single or double displacement reactions also involve rearrangements of atoms.
A single exchange reaction is given below.
Zn+H2SO4→ZnSO4+H2
In this reaction H of H2SO4 is exchanged with Zn.
A double exchange reaction is given below.
NaCl+AgNO3→AgCl+NaNO3
In this case, Ag is exchanged with Na so AgCl and NaNO3 is formed.
Thus, it is clear that atoms rearrange to form new products.
