Answer:

<u>1 mole of Fe and 1.5 moles of CO2</u>

Explanation:

<u>Fe2O3 + CO → Fe + CO2</u>

This is a trick question.  The equation is not balanced properly.  To start, note that one molecule of Fe2O3 contain 2 Fe atoms, while there is only 1 Fe atom on the product side.  And the oxygens are also missing (from 4 to 2).  We cannot use this equation, as written.

Here's one that is balanced:

<h2><u>Fe2CO3 + 3CO = 2Fe + 3CO2</u></h2>

<u>I'll use this one to answer the question.</u>

1.  <u>If 3 moles of Fe2O3 react with 1.5 moles of CO, how many moles of each product are formed?</u>

The balanced equation tells us that 1 mole of Fe2O3  will react with 3 moles CO to produce 2 moles of Fe and 3 moles of CO2.  <u><em>If we had enough CO</em></u>,  3 moles Fe2O3 will produce 6 moles of Fe and 9 moles of CO2.  But note that we'd also need 9 moles of CO for a complete reaction.  We only have 1.5 moles, probably due to Stanley, our new manager.  So we're limited by the CO, and we'll have to delete our first analysis and work from 1.5 moles of CO.

<h2>If we have 1.5 moles CO, we'll produce:</h2><h2> <u>1 mole of Fe and 1.5 moles CO2.</u></h2>

What is the mass of H2O produced when 14.0 grams of H2 reacts completely with 2.0 grams of O2?
Vladimir79 [104]
Balanced chemical equation:

2 H2 + 1 O2 = 2 H2O

4 g H2  -------> 32 g O2 -----------> 36 g H2O
   ↓                       ↓                             ↓
14.0 g ---------> 2.0 g O2 ----------> mass H2O ?

32 * mass H2O = 2.0 * 36

32 * mass H2O = 72

mass of H2O = 72 / 32

mass of H2O = 2.25 g

hope this helps!.

Use the formula: PV=nRT<br><br> If P=12, V=22.4, R=.0821 and T=100, then what would n=?
Lina20 [59]
PV=nRT \\ (12)(22.4)=n(.0821)(100) \\ 268.8=8.21n \\ 268.8/8.21=8.21n/8.21 \\ n=32.74
n ≈ 32.74
Hope this helps!
