Calculate the number of moles of iron (III) oxide (Fe 2 O 3 ) produced from 112 L of oxygen (O 2 ) in the following reaction

4Fe(s) + 3O2 (g) = 2Fe2O3 (s)

3.33 moles is the required answer.

Explanation:

We're going to use proportion to find the number of moles of iron oxide.

Actual no. of moles of oxygen =   (Since one mole at STP = 22.4 L)

= 5

Putting the values in the proportion.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.
