Question

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

Answer 1

The coefficient for sulfuric acid wen reaction between calcium phosphate and phosphoric acid occurs is

three (3)

Step-by-step explanation

write a balanced chemical equation for the reaction

that is

Ca3(PO4)2 + 3 H2SO4 →2 H3PO4 + 3CaSO4

since coefficient is number in front of a chemical formula the coefficient of H2SO4 is 3
