what is the empirical formula of a compound that is found to consist of 56% chorine and no other element except iron

FeCl₂

Explanation:

Empirical formula is the simplest formula of a compound.

Mass percentage of Chlorine  = 56%

Mass percentage Iron  = 100  - 56  = 44%

                                                              Elements  

                                                 Fe                                 Cl

Percentage mass                    44                                  56

moles                                      44/55.85                   56/35.5

                                                  0.79                         1.56

Divide by the smallest

number                                    0.79/0.79                 1.56/0.79

                                                        1                                 2

The empirical formula of the compound is FeCl₂

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.  

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
