Rank the following four acids in order of increasing bronsted acidity : h2f+ , ch3oh, (ch3)2oh+ , ch3sh2+

Explanation:

Bronsted acids are the species which donate protons.

In the given species, we can see that fluorine is the most electronegative atom hence, will not give proton easily. Therefore, its acidity will be the least.

Similarly, sulfur is also electronegative but less electronegative than fluorine atom. Hence, acidity of is slightly more than .

Whereas will have highest bronsted acidity and will be less acidic than .

Thus, we can conclude that order of increasing bronsted acidity is as follows.

      < < <  

answer; economic order quantity;

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
