Read the chemical equation.
Sladkaya [172]

Answer:- D. 1.8 moles of Fe and 2.7molCO_2 .

Solution:- The balanced equation is:

Fe_2O_3+3CO\rightarrow 2Fe+3CO_2

let's first figure out the limiting reactant using the given moles and mol ratio:

1.8molFe_2O_3(\frac{3molCO}{1molFe_2O_3})

= 5.4 mol CO

From calculations, 5.4 moles of CO are required to react completely with 1.8 moles of Iron(III)oxide but only 2.7 moles of CO are available. It means CO is limiting reactant.

Products moles depends on limiting reactant. Let's calculate the moles of each reactant formed for given 2.7 moles of CO.

2.7molCO(\frac{2molFe}{3molCO})

= 1.8 mol Fe

2.7molCO(\frac{3molCO_2}{3molCO})

= 2.7molCO_2

So, the correct choice is D.  1.8 moles of Fe and 2.7molCO_2 are formed.

enyata [817]

Sulfur-32 Information

This element is absorbed by plants from the soil as sulphate ion. Sulfur has 23 isotopes, 4 of them are stable. Sulfur is used in matches, gunpowder, medicines, rubber and pesticides, dyes and insecticides.

<h3>Which isotope of sulfur contributes the least to its mass number?</h3>

Sulfur (16S) has 23 known isotopes with mass numbers ranging from 27 to 49, four of which are stable: 32S (95.02%), 33S (0.75%), 34S (4.21%), and 36S (0.02%).

<h3>What is the use of Sulphur 35 isotope?</h3>

A radioactive sulfur isotope; a beta emitter with a half-life of 87.2 days; used as a tracer in the study of the metabolism of cysteine, cystine, methionine, and other compounds; also used to estimate, with labeled sulfate, extracellular fluid volumes.
