Homework Help: Writing chemical equations w/ catalysts

  1. Nov 30, 2008 #1
    hi. for a science lab in school we were discussing/exploring chemical equations...
    we had hydrogen peroxide (H2O2) which was catalyzed by potassium iodide (KI)
    for our lab report we need links to a website which describes how to properly write equations w/ catalysts. so firstly is this right:

    2(H2O2) [yield w/ KI above the sign] 2(H2O) + O2

    as a note, if i put 2 then parentheses it means that 2 is the coefficient.
    secondly, could anybody provide me with helpful links or an explination to why the above equations is right (or wrong if it is) and why? i'd like an explination and a few links so i could finish my project and do well on it.

    i'd appreciate an answer ASAP. thanks <3

    another thing, what would that problem look like in words?

    something like this id imagine (but not positive):

    hydrogen peroxide (L) catalyzed by a potassium iodide crystal

    You are more or less OK, you may want to use word "decomposition". As for finding links - google seems to be the best idea. You may want to limit your searches to .edu sites, try something like "hydrogen peroxide decomposition site:edu"

    okay, thank you very, very much.
    this really helped, i found a perfect website! :]

    (and the fact that it was a decomp equation really helped me too.)
    thanks again.
