Question

The number of components in a system containing 1 mole of nh4cl, 0.5 mole of nh3 and 0.5 mole of hcl are

Answer 1

Answer: 3 components NH3,H^+,Cl^-

Explanation: 1.5 moles of NH3, 1.5 moles of H^+, 1.5 moles of Cl^-

Answer 2

Answer:

0.5 mole of NH4CL

Explanation:

According to the given reaction we can write ;

Reaction  :  NH3 + HCL → NH4Cl

moles :          0.5       0.5         1

from equation we can deduce the facts that = 1 mole of NH3 react with 1 mol of HCL to give 1 mol of NH4CL

∴ 0.5 mol of NH3 will react with 0.5 mol of HCL to give 0.5 mole of NH4CL

hence excessive amount of NH4CL is present in system by 0.5
