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?

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

three (3)

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

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
