Plz help!! 10 points! Chopin piano Waltz in a minor Op. 34 No. 2 (Grande Valse brilliante/Waltz #3)?

I'm playing Chopin Waltz in a minor Op. 34 No. 2 and I need to know if in the Lento part of the piece, are the right hand chords tied or slurred? If they are tied, what notes to I not repeat? Also, does the right hand have tied notes in the 3-5 lines from the end? Thank you sooo much! 10 points for the best answer!
