What mass of carbon monoxide is needed to react with 2.08 kg of iron oxide? > Fe^2O^3 + 3CO --> 2Fe + 3CO^2 20 points, plz help and plz show how you work

I WILL MARK YOU BRAINIEST IF U ANSWER WITH FULL WORKING OUT!

The mass of carbon monoxide required is 1.094 kg

Explanation:

The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:

......(1)

Given mass of iron (III) oxide = 2.08 kg = 2080 g          (Conversion factor: 1 kg = 1000 g)

Molar mass of iron (III) oxide = 159.69 g/mol

Plugging values in equation 1:

The given chemical equation follows:

By the stoichiometry of the reaction:

If 1 mole of iron (III) oxide reacts with 3 moles of CO

So, 13.02 moles of iron (III) oxide will react with = of CO

Molar mass of CO = 28.01 g/mol

Plugging values in equation 1:

Hence, the mass of carbon monoxide required is 1.094 kg

it's c. elements are placed in rows based on how may valencies electrons have.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
