Homework Help: chemistry-net ionic equations

Posted by Jon on Sunday, August 28, 2005 at 5:06pm.

Whats the net ionic equation for the decomposition of hydrogen peroxide (H202)? I know that it decomposes into water and O2 but is H202->H20+O2 the net ionic or does the H2 and O2 split up to be H2 + O2 -> H20+O2 and if so is the net ionic then just H2->H20??

The H ion remains the same. The peroxide ion O- changes to O-- and O2 (zero oxidation state)


O- >>> O2 + O--

You balance it. Repost if necessary

potassium thiocyanate + iron (III) nitrate

H3PO4 -
