Please Help chemistry question?
What is the sum of the sum of the stoichiometric reaction coefficients in the balanced total ionic equation for the reaction of calcium hydroxide with hydrobromic acid, HBr? I get a total of 11 but it says it is wrong.
For this one to:KOH(aq) + H3PO3(aq) → K3PO3(aq) + H2O(l). I get a total of 17 but it is also wrong.

The total ionic equation for the reaction of calcium hydroxide with hydrobromic acid :
Ca(OH)₂ + 2HBr → CaBr₂ + 2H₂O
The sum of stoichiometric reaction coefficients = 1 + 2 + 1 + 2 = 6
The balanced second equation is :
3KOH + H₃PO₃ → K₃PO₃ + 3H₂O
The sum of stoichiometric reaction coefficients = 3 + 1 + 1 + 3 = 8
