How many moles of Iron (Fe) can be produced form 20 moles of carbon (C)?
2Fe2O3 + 3C —— 4Fe + 3C02

Moles of Fe produced = 40 moles

Given

Reaction

2Fe2O3 + 3C —— 4Fe + 3C02

20 moles of C

Required

moles of Fe

Solution

The reaction coefficient in a chemical equation shows the mole ratio of the reacting compounds (reactants and products)

From the reaction, mol ratio of Fe : C = 4 : 3, so mol Fe :

= 4/2 x mol C

= 4/2 x 20

= 40 moles

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
