PLEASE HELP with equations DUE TOMMOROW!

Post by ziggy08 »

Hi, :)

I've been working on this awhile with a few friends. Not sure about these equations:

acid/base:

K2CrO4 + H2SO4 ---> products? water, K2SO4 and?

products from previous equation + NaOH ---> ?

displacement of ligands:

CrK(SO4)2 . 12H2O ---(heat)--> CrK(SO4)2 + 12H2O

redox:

Cr(OH)4 + H2O2 ---> CrO4 + H2O

HNO3 + Cr(OH)4 ---> Cr(NO3)3 + H2O

K2CrO7 + zinc + HCl ---> ?


Thank you so much :)
