Answer:

Ionic bonds transfer ions while covalent bonds equally share them.

Explanation:

In an ionic bond, ions are transferred between each other and ionic bonds form between a metal and nonmetal.

Covalent bonds are equally shared between atoms and form between non metals only.

Specifically, nonpolar covalent bonds are perfectly symmetrical with equal distribution of electrons while polar covalent bonds are asymmetrical and there is a difference in electronegativity.

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
