HCl + Br(OH)2 = BrCl2 + H2O

HCl + Br(OH)2 = BrCl2 + H2O
This balance the equation
 2HCl + Br(OH)2 = BrCl2 + 2H2O

HCl + NaOH = NaCl + H2O

HCl + NaOH = NaCl + H2O
This balance the equation
HCl + NaOH = NaCl + H2O

ZnO + HCl = ZnCl2 + H2O

ZnO + HCl = ZnCl2 + H2O
This balance the equation
ZnO + 2HCl = ZnCl2 + H2O

HCL + Fe = FeCl2 + H2

Fe + HCl = FeCl₂ + H₂
This balance the equation
Fe + 2HCl = FeCl₂ + H₂

HCL + Na2CO3 = NaCL + CO2 + H2O

HCL + Na2CO3 = NaCL + CO2 + H2O
This balance the equation
2HCL + Na2CO3 = 2NaCL + CO2 + H2O

Na + H2O = NaOH + H2

Na + H2O = NaOH + H2
This balance the equation
2Na + 2H2O = 2NaOH + H2
