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>

Briefly compare and contrast the relative resistance to ph change of the seven solutions
JulsSmile [24]
PH  stands for "Potential Hydrogen" and the PH scale ranges from 0-14. PH refers to the ability to attract hydrogen ions.

The PH of a solution either indicates acidity of the solution or alkalinity of the solution. A solution which has PH 7 above is a base solution where a solution with PH less than 7 is an acidic solution.

State whether the following statements are true or false (with justification). (a) 1 mol of N2 has more molecules than 1 mol of
MAVERICK [17]

Answer:

A. False.

Every substance contains the same number of molecules i.e 6.02x10^23 molecules

B. False.

Mass conc. = number mole x molar Mass

Mass conc. of 1mole of N2 = 1 x 28 = 28g

Mass conc. of 1mol of Ar = 1 x 40 = 40g

The mass of 1mole of Ar is greater than the mass of 1mole of N2

C. False.

Molar Mass of N2 = 2x14 = 28g/mol

Molar Mass of Ar = 40g/mol

The molar mass of Ar is greater than that of N2.

Box 1
Alex73 [517]

10g

Explanation:

Box 1, Mass of A = 10g

Box 2, Mass of B = 5g

Box 3, = 1A + 1B

Unknown:

Mass of B that would combine with mass of 20g of A

Solution:

   Mass ratio of A to B:

   \frac{mass of A}{mass of B} = mass ratio

           \frac{10}{5} = mass ratio

        The mass ratio of A to B = 2: 1

Now, number of B that will combine with 20g of A;

       

           \frac{mass of A}{mass of B} = mass ratio

               \frac{20}{mass of B} = \frac{2}{1}

                     Mass of B = 10g

10g of B would combine with 20g of A

The compound methylamine, CH3NH2, is a weak base when dissolved in water. Write the Kb expression for the weak base equilibrium
Veronika [31]

Answer:

Kb = [CH₃NH₃⁺] × [OH⁻] / [CH₃NH₂]

Explanation:

According to Brönsted-Lowry acid-base theory:

  • An acid is a substance that donates H⁺.
  • A base is a substance that accepts H⁺.

When methylamine reacts with water, it behaves as a Brönsted-Lowry base, according to the following reaction.

CH₃NH₂(aq) + H₂O(l) ⇄ CH₃NH₃⁺(aq) + OH⁻(aq)

The basic equilibrium constant (Kb) is:

Kb = [CH₃NH₃⁺] × [OH⁻] / [CH₃NH₂]
