I have these reactions and can't figure out what to do or where to go for help so can anyone help?

(1) Te + HNO₃ + H₂O ---> TeO₂ + ?

(2) TeO₂ + HCl ---> ?

(3) TeO₂ + NaOH ---> ?

(4) TeO₂ + NaOH + BaCl₂ ---> ? (yellow solution with a precipitate)

Code: Select all

Te + 4 HNO₃ = TeO₂ + 4 NO₂ + 2 H₂O

TeO₂ + 4HCl = TeCl₄ + 2H₂O

TeO₂ + 2NaOH =Na₂TeO₃ + H₂O

TeO₂ + 2NaOH + BaCl₂ = BaTeO₃ + 2NaCl + H₂O

Hope that helps

Thank you very much. I knew that Se and Te reacted similarly but I couldn't find the reactions I needed.

Thanks again
