Title: Please Help MEEEEEEEEEEEEEEE!
Post by: edwardjr.1326 on November 26, 2008, 06:22:24 PM
Does anyone know how to write the balanced chemical equation for the reaction of magnesium hydroxide with hyposulfurous acid to produce magnesium hyposulfite and water. Please your help would be greatly appreciated I've been trying to do this for days now.

Well, since you know what all the compounds are, put the reactants on the left of the arrow and the products on the right and balance it.

And please don't shout (see point 5 of http://www.learnthenet.com/english/html/65mailet.htm (http://www.learnthenet.com/english/html/65mailet.htm))

hmmmm

ok

2Mg(OH)2(aq) + 2H2S2O4(aq)-----> 2MgS2O3 +5H20

H:10                                           
O:12
Mg:2
S:2


oooo crap that is hard.. but that ain't the answer.. I'm missing a friggen oxygen somewhere.... someone help i wanna noe the answer too

TWOFOUSAND:, you've picked the wrong formula for a reactant, can you fix it?  Anyway, if you're in the mood to work with Java applets, you can go to this page here:  http://www.trimen.pl/witek/calculators/wspolczynniki.html the goofy examples on that page show you, that balancing chemical  equations is just algebra, with compounds as variables instead of x, y, or z.

Let's see  :)

2MgOH + H2S2O4 :rarrow: 2MgSO2 + H2O

Looks pretty balanced to me  ;D

It is not THAT easy. Some reactions can't be easily balanced by algebraic method.
