if iron pyrite, fes2, is not removed from coal, oxygen from the air will combine with both the iron and the sulfur as coal burns. if a furnace burns an amount of coal containing 198.20 g of fes2, how much so2 (an air pollutant) is produced?
4 fes2 + 11 o2 → 2 fe2o3 + 8 so2
select one:
a. 211.7
b. 52.92
c. 590.8
d. 582.1

First we need to calculate the number of moles of FeS:

number of moles = mass (grams) / molecular mass (g/mol)

number of moles of FeS = 198.2/120 = 1.65 moles

From the chemical reaction we deduce that:

if            4 moles of FeS produces 8 moles of SO

then  1.65 moles of FeS produces X moles of SO

X = (1.65×8)/4 = 3.3 moles of SO

Now we can calculate the mass of SO:

mass (grams) = number of moles × molecular mass (grams/mole)

mass of SO = 3.3×64 = 211.2 g

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
