Balancing Chemical Equations- Please Help!!!!!

[rachelk]

Hi , I was just wondering if anyone would be able to help me balance this equation:

Na₂Cr₂O₇.2H₂O + H₂SO₄ = H₂CrO₄ + Na₂SO₄ + H₂O

I have been stuck on this for a while now and would appreciate any help

Na₂Cr₂O₇* 2 H₂O + H₂SO₄ => 2 H₂CrO₄ + Na₂SO₄ + H₂O

Na₂Cr₂O₇* 2 H₂O + H₂SO₄ => 2 H₂CrO₄ + Na₂SO₄ + H₂O splatoon 3

why is * 2 H₂O?

You wrote it in beginning. Crystal water is attached. Na₂Cr₂O₇× 2 H₂O .In this Form you can buy this salt. Of course there is also a dry Version without crystal water available.
