5. Some undiluted acids are more corrosive when diluted
wlad13 [49]

Answer:

The correct answer is : due to the hydrogen ions reacts and release high amount of energy with the strong acid.

Explanation:

Diluted acids are more corrosive then undiluted due to the presence of more H+ ions than the undiluted acids. The More the H+ ions are added the more corrosive the acid is.

When water is mixed with strong acid the hydrogen ions reacts with acid ions and a exothermic reaction takes place that release high amount of energy which boils violently, to avoid any accident it is advised to lab workers to wipe  if any splash self before washing.

Thus, the correct answer is : due to the hydrogen ions reacts and release high amount of energy with the strong acid.

tester [92]

<span>a.       </span>The frequency of the dominant allele: ___0.4______

<span>b.      </span>The frequency of the recessive allele: ____0.6_____

<span>c.       </span>The percentage of mice that are homozygous dominant: __16%_______

<span>d.      </span> The percentage of mice that are heterozygous: _48%________

<span>e.      </span>The percentage of mice that are homozygous recessive: __36%_______

 

Let us assign the dominant allele (that of brown hair) letter R while

We assign the recessive allele (that of white hair) letter r

We then note down the Hardy-Weinburg equation p2 + 2pq + q2 = 1

Brown fur population (p2 + 2pq) = 64% = 0.64

White fur population (q2) = 36% = 0.36

Then we also remember that the frequencies of both allele add up to 1 (p + q = 1);

Therefore q = ü.36 = 0.6

P = 1 – q = 1 – 0.6 = 0.4

The heterozygous population will be 2*0.6*0.4 = 0.48 =  48%

Homozygous domain population will therefore be (64% - 48%) = 16%
