Iron metal is produced from the mineral hematite (Fe2O3) and pure carbon, as given by the equation: Fe2O3 (s) + C (s)  -> Fe (s) + CO2 (g) [unbalanced]

Balance this equation. Then, use the mole ratios therein to perform the calculations below.

a. How many moles of C are required to completely react with 14.251 moles of Fe2O3 (hematite)?

b. How many moles of Fe2O3 must react to generate 0.986 moles of pure iron?

c. How many moles of CO2 will be generated if 2.774 moles of carbon completely reacts?

d. What is the limiting reactant?

e. Calculate the mass of excess reactant that remains when the reaction is complete.

f. When this reaction is performed in the laboratory, the percent yield of CO2 is 72.6%. What was the experimental yield of CO2?

wanahton purified a portion of water with 900 grams of contaminants. each hour, a third of the contaminants was filtered out.

let g(n) be the amount of contaminants (in grams) that remained by the beginning of the nth hour. g is a sequence, what kind of sequence is it, arithmetic or geometric? then, write an explicit formula for the sequence, g(n)=

explanation:

answer; i believe the correct answer is (c) /// is a homogeneous mixture of gaseous substance nitrogen,oxygen and smaller amounts of other substancesmixtures can be either ( homogeneous or heterogeneous)plz check first good luck
