Use bond energies to determine δhrxn for the reaction between ethanol and hydrogen chloride. ch3ch2oh(g)+hcl(g)âch3ch2cl(g)+h2o
Alex
For this reaction to proceed, the following bond breaking should occur: 
*one C-O bond* one H-Cl bond
After, the following bond formations should occur:*one C-Cl bond*one O-H bond
Now, add the bond energies for the respective bond energies which can be found in the attached picture. For bond formations, energy is negative. For bond breaking, energy is positive.
ΔHrxn = (1)(358) + (1)(431) + 1(-328) + 1(-463) =<em> -2 kJ</em>

5. A sample of pure acetyl salicylic acid had a mass of 0.268 grams. It was dissolved in NaOH and diluted to 500.00mL in a volum
Elza [17]

Answer:

a. 5.36x10⁻⁴ g/mL

b. 4.29x10⁻⁵ g/mL

Explanation:

As the units for concentration are not specified, I'll respond using g/mL.

a. We <em>divide the sample mass by the final volume</em> in order to <u>calculate the concentration</u>:

  • 0.268 g / 500 mL = 5.36x10⁻⁴ g/mL

b. We can use C₁V₁=C₂V₂ for this question:

  • 8.00 mL * 5.36x10⁻⁴ g/mL = C₂ * 100.00 mL
  • C₂ = 4.29x10⁻⁵ g/mL
