Can you use negative coefficients to balance chemical equations?
« on: December 07, 2004, 06:24:16 PM »
Can you use negative coefficients to balance chemical equations?  I'm having trouble on this particular problem:
Ca(AlO2)2  + HCl--->AlCl3  +  CaCl2 + H2O

PLEASE HELP A.S.A.P

No, you should be able to do it with positive coefficients. Don't give up, keep trying.

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

Ca(AlO2)2 + 8HCl -> 2AlCl3 + 4H2O + CaCl2
