balancin an equation!
hello everybody,
i just got back from my chemistry class, with some homework...
it s about balancin equations (hard ones) and they are relating to the lesson of oxidation-reduction...
here is one of them that i have to balance--
if someone can show me the steps to take, that would be awesome :) because i have like 5 more to do...
Al + H2SO4 --> Al 3+ + SO4 2- + SO2 + H2O
thank you :)
oh yeah, the problem in this equation is that i have SO4 2- and SO2
so to determine the number of oxydation for S
should it be -8 or -4 ==> should i use SO4 -2 or SO2
when i know what to use, i ll see the change of this number, then what ?
