One of the reactions in a blast furnace used to reduce iron is shown above. how many grams of fe2o3 are required to produce 15.5 g of fe if the reaction occurs in the presence of excess co? a.11.1 g b.22.1 g c.30.0 g d.44.2 g

Answer : The correct option is, (b) 22.1 g

Solution : Given,

Mass of iron = 15.5 g

Molar mass of iron = 56 g/mole

Molar mass of = 160 g/mole

First we have to calculate the moles of iron.

Now we have to calculate the moles of .

The balanced reaction is,

From the balanced reaction, we conclude that

As, 2 moles of iron obtained from 1 mole of

So, 0.276 moles of iron obtained from mole of

Now we have to calculate the mass of

Therefore, the amount of required are, 22.1 grams.

there is none because earth is stationary and flat.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
