gregori [183]

117.22 g are needed to react with an excess of Fe2O3 to produce 156.2 g of Fe.

Explanation:

                  Moles of Fe = Mass of Fe in grams / Atomic weight of Fe

                                        = 156.2 / 55.847

                  Moles of Fe  = 2.79.

The ratio between CO and Fe id 3 : 2.

                  Moles CO needed  = 2.79 * (3 / 2)

                                                   = 4.185.

 To calculate Atomic weight of CO,

                  Atomic weight of carbon = 12.011

                  Atomic weight of oxygen= 15.9994

        Atomic weight of CO = 12.011 + 15.9994 = 28.01 g / mol.

                 Mass of CO   = 4.185 * 28.01 = 117.22 g.

Valence electrons are found:
eduard
Valence electrons are found AT THE OUTERMOST SHELL OF AN ATOM.
Valence electron refers to those electrons that are located furthest away from the nucleus of an atom, that is, they are found at the outermost shell. Valence electrons determine the chemical properties of an element and they are the only ones that get involved in chemical reactions with other elements.
