Given the unbalanced reaction, Fe + S > Fe S , how 8 2 3
many moles of each reactant are needed to produce 1.50 moles of iron (III) sulfide? (balance equation first)

The answer to your question is 3 moles of Fe and 4.5 moles of S

Explanation:

Data

moles of Fe = ?

moles of S = ?

moles of Fe₂S₃

Unbalanced chemical reaction

                    Fe   +  S   ⇒    Fe₂S₃

             Reactants    Elements    Products

                     1                  Fe                2

                     1                   S                 3

Balanced chemical reaction

                    2Fe   +  3S   ⇒    Fe₂S₃

             Reactants    Elements    Products

                     2                  Fe                2

                     3                   S                 3

-Calculate the moles of each reactant

                  2 moles of Fe 1 mol of Fe₂S₃

                 x                       1.5 moles Fe₂S₃

                               x = (1.5 x 2) / 1

                                x = 3 moles of Fe

-Calculate the moles of S

                  3 moles of S 1 mol of Fe₂S₃

                  x                     1.5 moles of Fe₂S₃

                                x = (1.5 x 3) / 1

                                x = 4.5 moles of S

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
