Answer:

45.45 ml of dimethyl sulfoxide

Explanation:

density of dimethyl sulfoxide is 1.10 g/10⁻³L which is 1.10 g/mL

now we devise the next reasoning:

If           1.10 g of dimethyl sulfoxide have a volume of 1 mL

Then     50 g of dimethyl sulfoxide have a volume of X mL

X = (50 × 1) / 1.10 = 45.45 ml of dimethyl sulfoxide

Which of the following buffer systems would you use if you wanted to prepare a solution having a pH of approximately 9.5?Which o
zalisa [80]

Answer:

b. 0,08M NH₄⁺ / 0,12M NH₃

Explanation:

<em>The buffers are:</em>

<em>a. 0,08M H₂PO₄⁻ / 0,12M HPO₄²⁻</em>

<em>b. 0,08M NH₄⁺ / 0,12M NH₃</em>

It is possible to find out the pH of a buffer using Henderson-Hasselbalch formula:

<em>pH = pka + log₁₀ [A⁻] / [HA] </em><em>(1)</em>

Where A⁻ is the conjugate base of the weak acid, HA.

a. For the system H₂PO₄⁻ / HPO₄²⁻ pka is <u><em>7,198</em></u>. Replacing in (1)

pH = 7,198 + log₁₀ [0,12] / [0,08]

<em>pH = 7,37</em>

That means this buffer system don't have a pH of approximately 9,5

b. For the system NH₄⁺ / NH₃ pka is <em><u>9,3</u></em>. Replacing in (1)

pH = 9,3 + log₁₀ [0,12] / [0,08]

<em>pH = 9,50</em>

That means this buffer system is the buffer you need to use.

I hope it helps!

For the gas phase decomposition of 1-bromopropane, CH3CH2CH2BrCH3CH=CH2 + HBr the rate constant at 622 K is 6.43×10-4 /s and the
Radda [10]

Answer is: activation energy of this reaction is 212,01975 kJ/mol.<span>
Arrhenius equation: ln(k</span>₁/k₂) = Ea/R (1/T₂ - 1/T₁).<span>
k</span>₁ = 0,000643 1/s.<span>
k</span>₂ = 0,00828 1/s.

T₁ = 622 K.

T₂ = 666 K.

R = 8,3145 J/Kmol.

<span> 1/T</span>₁ = 1/622 K = 0,0016 1/K.<span>
1/T</span>₂ = 1/666 K = 0,0015 1/K.<span>
ln(0,000643/0,00828) = Ea/8,3145 J/Kmol · (-0,0001 1/K).
-2,55 = Ea/8,3145 J/Kmol </span>· (-0,0001 1/K).<span>
Ea = 212019,75 J/mol = 212,01975 kJ/mol.</span>
