Answer:

Number of moles of Fe = 10 mol

Number of moles of CO₂ = 15 mol

Explanation:

Given data:

Number of moles of iron oxide = 5 mol

Number of moles of carbon monoxide = 25 mol

Number of moles of product = ?

Solution:

Fe₂O₃ + 3CO   →  2Fe + 3CO₂

Now we will compare the moles of reactant with product.

                  Fe₂O₃        :         Fe

                     1             :          2

                    5             :         2×5 = 10 mol

                Fe₂O₃        :         CO₂

                     1             :          3

                    5             :         3×5 = 15 mol

                  CO           :         Fe

                     3             :          2

                    25             :         2/3×25 = 16.7 mol

                  CO            :         CO₂

                     3             :          3

                    25             :         25

Less number of moles of Fe and CO₂ are formed by iron oxide thus it will act as limiting reactant while CO is inn excess.

Polished metals have a metallic luster, which means that?
DochEvi [55]
Metallic luster refers to the way light casts off of a mineral. Polished metals such as gold have a metallic luster, which makes them look bright and shiny, and reflect more light than other minerals. There are also minerals that have metallic luster, but are not shiny or reflect much light, which is called dull metallic luster. 

Metallic luster - bright, shiny
Dull metallic luster - not shiny
