The theoretical yield of ammonia in an industrial synthesis was 550 kg, but only 480 kg was obtained. what was the percentage yield of the reaction?

Theoretical yield 550 kg - 100%

Actual yield 480 kg - x%

x= 480*100/550 ≈ 87.3 %

Percentage yield ≈ 87.3 %.

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.
