Explanation:
Detailed explanation-1: -When non-metallic oxides mix with water, it forms an acid that dissociates to give hydrogen ions, thus they are acidic in nature. The nature of non-metallic oxide can be explained with the help of a given reaction.
Detailed explanation-2: -Hence, the given statement is “True".
Detailed explanation-3: -Most of the metals form acidic oxides and nonmetals form basic oxides.
Detailed explanation-4: -Manganese heptoxide ( M n 2 O 7 ) forms permanganic acid. Chromium trioxide ( C r O 3 ) forms chromic acid. Manganese heptoxide and Chromium trioxide are acidic oxides. The oxidation number of M n i n M n 2 O 7 i s + 7 (highest oxidation number of Mn) More items
