Given: Unbalanced chemical reaction: _KOH + _H₃PO₄ = _K₃PO₄ + _H₂O

Required:

Units of all quantities must be shown in all calculations.

A.) Balance the reaction by providing the stoichiometric coefficients in the spaces indicated based on conservation of mass only (i.e., not redox or charge). Use whole numbers for the coefficients.

B.) How much phosphoric acid (H₃PO₄) is needed to react completely with 250 g of KOH in the reaction shown above? How much potassium phosphate is produced?

C.) What mass flowrate of phosphoric acid (H₃PO₄) would be needed to react completely the KOH if KOH was present in a 100 L/min flow stream at a concentration 500 mg/L? Express your answer in units of g-H₃PO₄/min.
