Answer:

pH = 3.215

Explanation:

From the given information;

Using the equation for the dilution of a stock solution:

Since moles of C5H5N = moles of HNO3

Then:

$M_{C_5H_5N}\times V_{C_5H_5N}= M_{HNO_3}\times V_{HNO_3}$

$0.0750 M \times 2.65 L = 0.407 M \times V_{HNO_3}$

$V_{HNO_3}= \dfrac{0.0750 M \times 2.65 L}{0.407 M}$

$V_{HNO_3}=488.33 \ mL$

The reaction between C5H5NH and H2O is as follows:

$C_5H_5N^+H + H_2O$ ⇄ $C_5H_5N + H_3O^+$

$Molarity \ of \ C_5H_5N^+H = \dfrac{moles}{addition \ of\ the\ total\ volume}$

$Molarity \ of \ C_5H_5N^+H = \dfrac{0.0750 \ M \times 2.65 \ L}{2.65 \ L + 0.48833 \ L}$

$Molarity \ of \ C_5H_5N^+H = \dfrac{0.19875 \ ML}{3.13833 L }$

$= \ 0.06333\ M$

Now, the next step is to draw out the I.C.E table.

$C_5H_5N^+H + H_2O$ ⇄ $C_5H_5N + H_3O^+$

I 0.06333 0 0

C - x x x

E 0.06333 -x x x

$K_a = \dfrac{10^{-14}}{1.7 \times 10^{-19}} \\ \\ K_a = 5.8824 \times 10^{-6}$

$K_a = \dfrac{[C_5H_5N][H_3O^+] }{[C_5H_5N^+H] } \\ \\ 5.8824 \times 10^{-6} = \dfrac{x^2}{0.06333 - x}$

Assuming x < 0.06333

$x^2 = 5.8824 \times 10^{-6} \times 0.06333$

Then

$x^2 = 3.72532392 \times 10^{-7} \\ \\ x= \sqrt{3.72532392 \times 10^{-7}} \\ \\ x = 6.1035 \times 10^{-4} \ M$

$[H_3O^+] = x = 6.1035 \times 10^{-4} \ M \\ \\ pH = -log (6.1035 \times 10^{-4}) \\ \\ \mathbf{\\ pH = 3.215}$

Are scorpions producer, herbivore, carnivore, scavenger, or decomposer.

olga nikolaevna [1]

Scorpions are carnivores as they attack and paralyze their prey by stinging them with its tail. Depending on the scorpion's size, they eat from the smallest of insects like cockroaches and crickets to larger creatures like mice, small rabbits, and birds.

In some protists, genetic information is transferred from one cell to the next. This transfer is called _____.

bearhunter [10]

conjugation

Binary fission is a reproduction process wherein one cell divides asexually into two cells forming two daughter cells. into In binary fission, the chromosome is being replicated in which the resultant prokaryote is exactly the same copy of the parental prokaryote which means to say that there is no chance for genetic diversity. However, prokaryotes can still share or even exchange genes through the mechanisms of transformation, transduction and conjugation.

Protein synthesis can be compared to building a doghouse. Sondra wanted to build a doghouse and found a book in the reference se

Nimfa-mama [501]

The correct answer is mRNA.

mRNA or messenger RNA is synthesized during the process of transcription, from DNA molecule which is used as a template. mRNA contains information about protein synthesis (translation) in the form of nucleotide triplets or codons.

In the example above: reference book is DNA molecule (template for copies), copies are mRNA, wood is amino acids (building blocks) and doghouse is protein.
