The discovery of the electron as a subatomic particle was a result of English physicist J.J. Thomson
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.

I don't think the question is complete
Answer:
19.39mph
Explanation:
To calculate speed, the formula; distance (d)/time(t) is used.
In this question, a distance of 40yards and a time of 4.22seconds is given. We need to convert the distance to miles and time to hours.
If 3600s = 1 hr
Then 4.22s will be 4.22/3600 hours
= 0.001172hours.
If 1760 yd = 1 mile
Then 40 yd will be 40/1760 miles
= 0.02272miles
Hence, the speed in miles per hour (mph) = 0.02272miles ÷ 0.001172hours
= 0.02272 ÷ 0.001172
= 19.38566
= 19.39
Therefore, the speed of the player is 19.39 miles per hour (mph).
