What do you mean? Is this for anyone stuck on the same question cause I don’t think that’s how it works lol
Answer:
Number of hydrogen sulfide molecule = 5.7672 x 10²³ (Approx)
Explanation:
Molar mass of H2S = (1x2) + 32 = 34 g
Total number of molecule = 34 / 35.50
Total number of molecule = 0.9577
Avogadro's number = 6.022 x 10²³
Number of hydrogen sulfide molecule = 0.9577 x 6.022 x 10²³
Number of hydrogen sulfide molecule = 5.7672 x 10²³ (Approx)
For
a first-order reaction, the rate law would be expressed as:<span>
r = dC / dt = -kC
Integrating it from time zero and
the initial concentration, Co, to time, t, and the final
concentration, C. We will obtain the first-order integrated law as follows:
ln C/Co= -kt
To determine the concentration of N2O in the system at a certain time, we simply substitute the given values from the problem statement
as follows:
</span>ln C / Co = -kt<span>
ln C / 10.9 = -0.76 (9.6)
e^ln C / 10.9 = e^-0.76 (9.6)
C / 10.9 = 6.78 x 10^-4
C= 7.39 x 10^-3 m
<span>
Therefore, the concentration of N2O in the system after 9.6 s would be 7.39 x10^-3 m.

Answer:
ΔHreaction = 263.15 kJ/mol
Explanation:
The reaction is as follow:
OH + CF₂Cl₂ → HOF + CFCl₂
You need to calculate the enthalpy of reaction and for this it is necessary to know the standard enthalpies for each of the compounds. These enthalpies are as follows and can be found in your textbook or on the Internet.
ΔHreaction = ∑ΔHproducts - ∑ΔHreactants
