I have 4 questions

1 What is the equation for the acid ionization constant of HI?

2 Give the oxidation numbers of all atoms in NaMnO4

3 An atom changes its oxidation number from -2 to -5. Is it oxidized or reduced? How many

electrons did it take to do this?

4 An atom changes its oxidation number from 0 to +2. Is it oxidized or reduced? How many

electrons did it take to do this?
