NO. There is no chlorine on the reactant side, so it cannot be balanced.
Nacl+Hcl+CaCO3
NaCl plus CaCO3 plus water
When NaHCO3 plus HCL reacted they forum two different substance that is H4CO3+NaCl, That is the balanced formula.
You need to know the amounts of reactants.
Balancing equation of FeCl2 and Na2CO3 yield 2NaCl and FeCO3
Yes
2h2s+o2-->2h2o+co2
No because you have an extra H. Sodium hydroxide is NaOH.
its balanced
C3h8 + 5o2 --> 3co2 + 4h2o
Ag+Ba yields no reaction.
2KClO3 --> 2KCl + 3O2
