Iron produced : 1.5 kg

<h3>Further explanation</h3>

Reaction

a) CaCO3→CaO + CO2

b) CO2 + C → 2CO

c) Fe2O3 + 3CO → 2Fe + 3CO2

mol CaCO₃ (MW=100,0869 g/mol) :

\tt \dfrac{1340}{100,0869}=13.39

mol CO₂ = mol CaCO₃ =13.39(reaction a)

mol CO = 2 x mol CO₂ = 26.78(reaction b)

mol CO(reaction c) = 1.5 mol CO from reaction b = 1.5 x 26.78 = 40.17

mol Fe(reaction c) = 2/3 x mol CO =

\tt \dfrac{2}{3}\times 40.17=26.78

Or we can cancel out the same compound in different sides from the sum of the three reactions to find mol Fe

a) CaCO3→CaO + CO2

b) CO2 + C → 2CO

c) Fe2O3 + 3CO → 2Fe + 3CO2

----------------------------------------------+

CaCO3 + Fe2O3 + C + CO + 3CO2 ⇒ CaO + 2Fe

mol Fe = 2 x mol CaCO3 = 2 x 13.39 = 26.78

mass Fe :

\tt 26.78\times 55.845~g/mol=1495.53~g\approx 1.5~kg

A sample of 17.0 M concentrated H2SO4 stock solution with a volume of 25.0 cm3 was diluted to final concentration of 5.0 M H2SO4
Art [367]

Answer:

60 cm³ of water

Explanation:

We'll begin by calculating the volume of the diluted solution. This can be obtained as follow:

Concentration of stock solution (C₁) = 17 M

Volume of stock solution (V₁) = 25 cm³

Concentration of diluted solution (C₂) = 5 M

Volume of diluted solution (V₂) =?

C₁V₁ = C₂V₂

17 × 25 = 5 × V₂

425 = 5 × V₂

Divide both side by 5

V₂ = 425 / 5

V₂ = 85 cm³

Thus, the volume of the diluted solution is 85 cm³

Finally, we shall determine the volume of water needed to dilute the solution. This can be obtained as follow:

Volume of stock solution (V₁) = 25 cm³

Volume of diluted solution (V₂) = 85 cm³

Volume of water =?

Volume of water = V₂ – V₁

Volume of water = 85 – 25

Volume of water = 60 cm³

Therefore, 60 cm³ of water is needed to dilute the solution.

What makes a charged object attract an uncharged object?
Ratling [72]

Answer:

its c I think C)

 

The reason for this is due to the phenomenon called "Charging by Induction". What that means is that when something with a charge, for example a negative charge, is brought near an uncharged one, it induces the opposite charge onto it (positive in this case) and therefore since opposites attract, it attracts it.

The reason for this is that since, just like a positive magnet rejects and pushed away like charges, the electrons hold a negative charge, they push away any electrons that may be in the neutrally charged item causing only protons to be left, thus creating an oppositely charged object. Or vice versa.

So whatever charge the object has, it induces the opposite charge into the uncharged object, causing the charges to move only in the uncharged one.

What are the pH of these solutions?
Tju [1.3M]

Answer:

The answer to your question is below

Explanation:

a)    HCl  0.01 M

      pH = -log [0.01]

      pH = - (-2)

     pH = 2

b)    HCl = 0.001 M

      pH = -log[0.001]

      pH = -(-3)

      pH = 3

c)    HCl = 0.00001 M

       pH = -log[0.00001]

       pH = - (-5)

      pH = 5

d) Distilled water

      pH = 7.0

e) NaOH = 0.00001 M

       pOH = -log [0.00001]

       pOH = -(-5)

       pH = 14 - 5

       pH = 9

f)  NaOH = 0.001 M

      pOH =- log [0.001]

      pOH = 3

      pH = 14 - 3

      pH = 11

g)   NaOH = 0.1 M

       pOH = -log[0.1]

       pOH = 1

       pH = 14 - 1

       pH = 13
