Blast furnaces extra pure iron from the iron(III) oxide in iron ore in a two step sequence. In the first step, carbon and oxygen react to form carbon monoxide:

2C(s)+O2(g)--->2CO(g)

In the second step, iron(III) oxide and carbon monoxide react to form iron and carbon dioxide:

Fe2O3(s)+3CO(g)--->2Fe(s)+3CO2(g)

Suppose the yield of the first step is 65.% and the yield of the second step is 94.%. Calculate the mass of oxygen required to make 6.0kg of iron.

Be sure your answer has a unit symbol, if needed, and is rounded to 2 significant digits.

Propane can be turned into hydrogen by the two-step reforming process. In the first step, propane and water react to form carbon monoxide and hydrogen:

C3H8(g)+3H2O(g)→3CO(g)+7H2(g)

In the second step, carbon monoxide and water react to form hydrogen and carbon dioxide:

CO(g)+H2O(g)→H2(g)+CO2(g)

Write the net chemical equation for the production of hydrogen from propane and water.

Copper (I) sulfide and oxygen react to form copper (I) oxide and sulfur dioxide:

In the second step, copper (I) oxide and carbon react to form copper and carbon monoxide:

Write the net chemical equation for the production of copper from copper (I) sulfide, oxygen, and carbon.

Iron(iii) oxide reacts with carbon to give iron and carbon monoxide.Fe2O3(s)+3c(s)_2Fe(s)+3CO(g).how many grams of C are required to react with 47.3 g of Fe2O3
