How might a reductive amination be used to synthesize phenylpropanolamine, an amino alcohol pharmaceutical derived from propanolamine? draw the structure of the aldehyde/ketone and the amine that would be used to synthesize this compound.

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 !

b is the correct answer

mark me brainliest and hope this

i'm pretty sure its b i might be wrong though!
