<span>There would be two electrons in the 1s orbital one oriented up and one oriented down. The other electron would be in the 1p orbital up or down. Remember that 1s can only hold 2 electrons at a time, and when it is filled there one electron is spinning up and the other is spinning down. After 1s, comes the 1p orbital which can hold 6 electrons. Until 3 electrons are spinning either up or down, the next one will have the next orientation.</span>

Solid iron (III) oxide reacts with hydrogen gas to form iron and water. How many grams of iron are produced when 440.23 grams of
Nookie1986 [14]

When 440.23 grams of iron(III) oxide are reacted with hydrogen gas, the amount of iron produced will be 307.66 grams

<h3>Stoichiometric calculation</h3>

From the equation of the reaction:

Fe_2O_3 + 3H_2 --- > 2Fe + 3H_2O

The mole ratio of iron(III) oxide to produced iron is 1:2.

Mole of 440.23 iron(III) oxide = 440.23/159.69 = 2.76 moles

Equivalent mole of produced iron = 2.76 x 2 = 5.52 moles

Mass of 5.52 moles of iron = 5.52 x 55.8 = 307.66 grams
