Question

The schematic diagram is given below :
Which of the following is an incorrect statement?
(a) A and E are chemically same.
(b) A and D are chemically same.
(c) D and E are chemically same.
(d) C and E are chemically same.

Answer 1

Answer:

a and d are chemically same

the question is not right the website question is that which of the following statements are correct so here is nh4cl which stands for ammonium chloride which directly changes into vapour that's why A and d

are chemically same

Answer 2

Answer:

The incorrect statement is (d) C and E are chemically the same.​

Explanation:

Step 1: A schematic diagram of a chemical process emphasises the roles of the individual parts and the linkages among them while downplaying the physical features of the containers, pipelines, valves, pumps, and other equipment that make up the system.

From the diagram we can conclude the following:

A represents ammonium chloride. When it is heated it forms vapors of ammonia (B) and HCl.

When A reacts with NaCl, the reaction is:

      NH₄Cl + NaOH --> NaCl + NH₃ (g) + H₂O.

Step 2: Out of the above products, ammonia can react with concentrated HCl to form NH₄Cl (D).

When D is shaken well with water, it dissociates into alkaline NH₄OH and acidic HCl.

Hence C is NH₃ and E is HCl.

So, A, D is ammonium chloride. E is HCl and B, C is ammonia.
