Question 12
F

A student compares the laboratory and industrial preparations of ammonium sulfate.

Statement 1: in industry, the ammonia and the sulfuric acid are first manufactured from raw materials such as air, natural gas, sulfur and water

Statement 2: the laboratory preparation is a continuous process, whereas the industrial preparation is a batch process

Statement 3: both methods form ammonium sulfate by the same reaction, 2NH3+H2SO4→(NH4)2SO4\mathrm{2NH_{3} + H_{2}SO_{4} \rightarrow (NH_{4})_{2}SO_{4}}2NH3​+H2​SO4​→(NH4​)2​SO4​
