Algebric Method for Chem Equation
« on: May 20, 2020, 07:37:08 AM »
Hello all :)
I am new here so sorry if this is under the wrong category!

So I am having a lot of exercises for university and one of them is balancing chemical equations with algebric method... and I am stuck with one for more than a week. Was hoping someone could help me?

NH3 + CO + Na2CO3  :rarrow: NaCN + CO2 +  H2 + H2O

I can't find enough expressions. I have managed to balance it with the half reaction method though to make sure its solvable (?).
Thanks in advance!!!!

This is a combination of two different reactions.
NH3 + CO + Na2CO3 = NaCN + H2O + CO2
and
CO + H2O = H2 + CO2
This set of reactions can be balanced in an infinite number of ways though number of water molecules limits multiplicity of the second reaction.
