Title: Sum of coefficients
Post by: Tom on June 11, 2004, 11:52:47 AM
Can anyone tell me what the balance the following chemical equation using the minimum integral coefficients would be? The sum of the coefficients is CaSO3 + HBr ? CaBr2 + SO2 + H2O.
 
   a.   5
   b.   6
   c.   7
   d.   8

ok

my teacher always told me to balance Hydrogen and Oxygen last

so here it goes

CaSO3 + 2HBr -> CaBr2 + SO2 + H20

answer is b.
