Question

Strontium phosphate reacts with sulfuric acid to form strontium sulfate and phosphoric acid. what is the coefficient for sulfuric acid when the equation is balanced using the lowest, whole-numbered coefficients?

Answer 1

Answer: The coefficient of sulfuric acid in the given equation is 3.

Step-by-step explanation:

The chemical equation for the reaction of strontium phosphate and sulfuric acid follows:

`Sr_3(PO_4)_2+3H_2SO_4\rightarrow 3SrSO_4+2H_3PO_4`

By Stoichiometry of the reaction:

1 mole of strontium phosphate reacts with 3 moles of sulfuric acid to produce 3 moles of strontium sulfate and 2 moles of phosphoric acid.

The given reaction is a type of double displacement reaction because here exchange of ions takes place.

Hence, the coefficient of sulfuric acid in the given equation is 3.
