How Do You Balence out this equation?

Question

CaCl2+NaHCO3+H2O=CaCO3+NaCl+H2O+CO2

Answer 1

mn : what a great resource!

hmmm... is it a redox question?

Answer 2

Answer: 2 (CaCl2) + 2(NaHCO3) + 2(H20) => 2(CaCO3) + 2(NaCl) + 2(H2) + Cl2 + O2

Steps:

CaCl2 + NaHCO3 + H2O => CaCO3 + NaCl + H2

There are 2 Cl's at the left but only 1 Cl at the right, therefore
CaCl2 + NaHCO3 + H2O => CaCO3 + 2(NaCl) + H2

There are 2 Na's at the right now but only 1 Na at the left, therefore
CaCl2 + 2(NaHCO3) + H2O => CaCO3 + 2(NaCl) + H2

There are 2 CO3's at the left now but only 1 CO3 at the left, therefore
CaCl2 + 2(NaHCO3) + H2O => 2(CaCO3) + 2(NaCl) + H2

There are 2 Ca's at the right but only 1 Ca at the left, therefore
2(CaCl2) + 2(NaHCO3) + H2O => 2(CaCO3) + 2(NaCl) + H2

There are 4 Cl's at the left but only 2 Cl's at the right,
but we cannot just add in another molecules to NaCl,
and that Cl cannot stand on its own, therefore
2(CaCl2) + 2(NaHCO3) + H2O => 2(CaCO3) + 2(NaCl) + H2 + Cl2*

There is an extra O at the left, but O cannot stand on its own, therefore
2 (CaCl2) + 2(NaHCO3) + 2(H20) => 2(CaCO3) + 2(NaCl) + 2(H2) + Cl2 + O2

The number of H2 is increased because of the increase of H20

Answer 3

How Do You Balence out this equation?
CaCl2+2NaHCO3+H2O=CaCO3+2NaCl+H2+H2O

Answer 4

I'm pretty sure thats impossible.. because if you add more Cl's to the right side, you have to add more Na to the left, then you have to add more C to the right, then more Ca to the left, the more Cl to the right and then it repeats and it will never balance

Answer 5

WTF...you cant balance that, you must have made a mistake.

you sure its NaCl?
