HOw do yo do 8HO2+6NO4---> ?

Please, give us the courtesy of checking your question for grammatical, spelling and Chemical errors.
HO2 doesn't exist, neither does NO4. What is a stoichiometry CONVERSION? "do" is the only word you have spelled correctly.
(I can be critical because I bear the eternal shame of having "Substoichiometric" misspelled in the title of one of my patents.)
