Separation of a mixture 4 (a) this set of questions is about the separation of a mixture of ch3ch2ch2ch2ch2ch2ch2ch2nh2, p-bromobenzoic acid and naphthalene. using your answers to the above questions, complete the following flow diagram by drawing relevant skeletal (line bond) structures. mixture in hexane contains _amine p-bromobenzoic acid naphthalene reaction with hcl (aq) hexane layer contains water layer contains reaction with nahco3 (aq) water layer hexane layer reaction with naoh(aq) reaction with hcl(aq)

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !

the answer your looking for is c).
