Answer:
HCl will dissociate more fully and produce more H₃O⁺ ions.
Explanation:
HCl is strong acid and it dissociate fully and produce more H₃O⁺ ions as compared to the HF.
Although H-F is stronger bond as compared to the HCl but stability of product also count, and fluorine ions F⁻ which are formed after dissociation are not more stable as Cl⁻ ions.
Both F⁻ and Cl⁻ are carried -1 charge, but in case of chloride ions negative charge is spread over large surface area while in case of fluorine it is restricted to small surface. Thus F⁻ are becomes unstable.
Thus in dissociation equilibrium is shifted to wards HF and cause lower dissociation.
The given question is incomplete, the complete question is:
A chemical engineer must calculate the maximum safe operating temperature of a high-pressure gas reaction vessel. The vessel is a stainless-steel cylinder that measures 18.0cm wide and 21.6cm high. The maximum safe pressure inside the vessel has been measured to be8.50MPa For a certain reaction the vessel may contain up to0.362kg of carbon dioxide gas. Calculate the maximum safe operating temperature the engineer should recommend for this reaction. Write your answer in degrees Celsius.Be sure your answer has the correct number of significant digits.
Answer:
The correct answer is 411 degree C.
Explanation:
The width of the vessel is 18.0 cm or 9.0 cm in radius and height of the vessel is 21.6 cm. In the given question, to find the volume of the cylinder, the formula to be used is pie r^2h
= 22/7 * (9)^2 * 21.6 cm^3
= 5498.7 cc
= 5.5 L
The value of 1MPa is 9.869 atm, therefore, the value of 8.5 MPa will be 83.89 atm.
The maximum safe operating temperature can be calculated by using the ideal gas equation, that is, P = nRT/V or T = PV/nR
= 83.89 atm * 5.5 L / (0.362*10^3 g/44g/mol) * 0.082 L atmK^-1mol^-1
= 683.9 K
= 683.9 - 273 = 410.9 degree C = 411 degree C.
Hence, the maximum safe operating temperature is 411 degree C.
Suppose that 0.25M IBr in a flask, the Kc at the given temperature is mathematically given as
Kc=0.00336814413
<h3>What is the Kc at the given temperature?</h3>
Generally, the equation for Chemical Reaction is mathematically given as
2IBr--->T2+8r_2
Therefore
K={I2*Br2}/IBR^2
K=x^2/(0.25-2x)^2
Kc=0.13M^2/0.224M^2
Kc=0.00336814413
In conclusion, the Kc at the given temperature
Kc=0.00336814413

Answer:
Mixtures
Explanation:
Mixtures are simply a physical combination of two or more substances. They can be separated based only by physical means, or by undergoing physical changes. A physical change alters a substance without changing its composition.
