Question

oxidation number of oxygen has been arranged in increasing

Answer 1

The highest possible state for the nonmetals is equal to the total number of electrons present in the valence (outermost) shell of the atom with a plus sign. Thus, the maximum oxidation states of nitrogen, sulphur and chlorine are +5 (as in HNO3), +6(as in H2SO4) and +7 ( as in HClO4) respectively.

Answer 2

Explanation:

oxidation number of oxygen has been arranged in increasing

When ethanol and acetic acid are mixed together in equimolar proportions, equilibrium is attained when 2/3rd of acid and alcohol are consumed.
