) In the Deacon process for the manufacture of chlorine, HCl and O2 react to form Cl2 and H2O. Sufficient air (21 mole% O2, 79%
LiRa [457]

Answer:

Here's what I get.

Explanation:

1. Write the chemical equation

\rm 4HCl + O$_{2} \longrightarrow \,$ 2Cl$_{2}$ + 2H$_{2}$O

Assume that we start with 4 L of HCl

2. Calculate the theoretical volume of oxygen

\text{V}_{\text{O}_{2}}= \text{4 L HCl} \times \dfrac{\text{1 L O}_{2}}{\text{4 L HCl}} = \text{1 L O}_{2}}

3. Add 35% excess

\text{V}_{\text{O}_{2}}= \text{1 L O}_{2}} \times 1.35 = \text{1.35 L O}_{2}}

4. Calculate the theoretical volume of nitrogen

\text{V}_{\text{N}_{2}} = \text{1.35 L O}_{2}} \times \dfrac{\text{79 L N}_{2}}{\text{21 L O}_{2}}} = \text{5.08 L N}_{2}}

4. Calculate volumes of reactant used up

Only 85 % of the HCl is converted.

We can summarize the volumes in an ICE table

           4HCl     +       O₂    +    N₂   →    2Cl₂   +   2H₂O

I/L:          4               1.35         5.08         0              0

C/L:  -0.85(4)        -0.85(1)        0      +0.85(2)   +0.85(2)

E/L:     0.60             0.50        5.08       1.70          1.70

5. Calculate the mole fractions of each gas in the product stream

Total volume = (0.60 + 0.50 + 5.08 + 1.70 + 1.70) L = 9.58 L

\chi = \dfrac{\text{V}_{\text{component}}}{\text{V}_\text{total}} = \dfrac{\text{ V}_{\text{component}}}{\text{9.58}} = \text{0.1044V}_{\text{component}}\\\\\chi_{\text{HCl}} = 0.1044\times 0.60 = 0.063\\\\\chi_{\text{O}_{2}} = 0.1044\times 0.50 = 0.052\\\\\chi_{\text{N}_{2}} = 0.1044\times 5.08 = 0.530\\\\\chi_{\text{Cl}_{2}} = 0.1044\times 1.70 = 0.177\\\\\chi_{\text{H$_{2}${O}}} = 0.1044\times 1.70 = 0.177\\\\

aleksley [76]

Answer:

Electrical Energy

Explanation:

There are a variety of chemical and mechanical devices that are called batteries, although they operate on different physical principles. A battery for the purposes of this explanation will be a device that can store energy in a chemical form and convert that stored chemical energy into electrical energy when needed.

Verdadero o falso.
marusya05 [52]

Answer:

True

Ammonia reacts as a nucleophile with alkyl halides to give primary amines in a nucleophilic substitution reaction. Yields are often poor as the product, a primary amine, RNH2, is itself a nucleophile and can react with more alkyl

A nitrile is a compound that contains a –CN (cyano) functional group with a carbon-nitrogen triple bond. The simplest organic nitrile is CH3–CN and is called acetonitrile, which is a good solvent for organic reactions. ... Structurally diverse nitrile-containing compounds are present in many medicinal drugs.

How much volume will 8.8 moles of gas fill at 0.12 atm at 56*C
Neporo4naja [7]

Answer:

2000 L

General Formulas and Concepts:

<u>Atomic Structure</u>

  • Moles
  • Temperature Conversion: K = °C + 273.15

<u>Gas Laws</u>

Ideal Gas Law: PV = nRT

  • P is pressure
  • V is volume (in L)
  • n is number of moles
  • R is gas constant
  • T is temperature (in K)

Explanation:

<u>Step 1: Define</u>

[Given] 8.8 moles gas

[Given] 0.12 atm

[Given] 56 °C = 329.15 K

<u>Step 2: Solve for </u><em><u>V</u></em>

  1. Substitute in variables [Ideal Gas Law Formula]:                                           \displaystyle (0.12 \ atm)V = (8.8 \ mol)(0.0821 \ \frac{L \cdot atm}{mol \cdot K})(329.15 \ K)
  2. Isolate <em>V</em>:                                                                                                           \displaystyle V = \frac{(8.8 \ mol)(0.0821 \ \frac{L \cdot atm}{mol \cdot K})(329.15 \ K)}{(0.12 \ atm)}
  3. Multiply/Divide [Cancel out units]:                                                                   \displaystyle V = 1981.7 \ L

<u>Step 3: Check</u>

<em>Follow sig fig rules and round. We are given 2 sig figs.</em>

1981.7 L ≈ 2000 L
