2C2H6 + 7O2 -> 4CO2 + 6H2O
By looking at the ethane I could see that I needed to put the 2 coefficient in front of it to make the oxygens come out even. Always balance O2 last in these combustion reactions.
The coefficient of HCl in the balanced equation is 2. This is because the balanced equation shows that 1 molecule of CaCl2 reacts with 1 molecule of H2CO3 to form 1 molecule of CaCO3 and 2 molecules of HCl.

The balanced equation should be 2Al + 6HCl -> 2AlCl3 + 3H2. Therefore, the coefficient of HCl is 6.
HCl + NaOH --> NaCl + H2O is balanced as you wrote it.But, since sodium is always soluble in water at temperatures below the boiling point of the solution, the net ionic equation for the reaction at temperatures lower than the boiling point would actually be: HCl + OH- --> Cl- + H2OOr, if the hydrochloric acid was already in solution, then simplyH+ + OH- ---> H2O
This equation is Al2O3 + 6 HCl = 2 AlCl3 + 3 H2O.
The coefficient of HCl in the balanced equation is 2. This is because the balanced equation shows that 1 molecule of CaCl2 reacts with 1 molecule of H2CO3 to form 1 molecule of CaCO3 and 2 molecules of HCl.

H2 + Cl2 --> 2HCl
The balanced equation should be 2Al + 6HCl -> 2AlCl3 + 3H2. Therefore, the coefficient of HCl is 6.

The balanced chemical equation for the reaction is: PCl3 + 3H2O → H3PO3 + 3HCl
The balanced chemical equation for the reaction between hydrochloric acid (HCl) and potassium (K) is: 2HCl + 2K -> 2KCl + H2.
The balanced chemical equation for the reaction is: ZnS + 2HCl → ZnCl2 + H2S
Ammonia plus hydrochloric acid produces ammonium chloride. NH3 + HCl → NH4Cl
The ionic equation for the reaction between hydrochloric acid (HCl) and methylamine (CH3NH2) is: HCl + CH3NH2 -> CH3NH3+ + Cl-
The balanced equation for BaCO3 + 2HI is BaCO3 + 2HI → BaI2 + H2O + CO2.
