George Tomlin, RMA, has been working for several years in a specialty practice. He applies for a position closer to his home wit

Semenov [28]

For George Tomlin, the best way to review the basic medical terminologies and methods is by visual as well as by auditory ways.

George can read the words carefully by going through them in books or from online resources.
He can listen carefully the words in online lectures and tutorials and understand the meaning of the terminologies.

When George encounters a new word :

he can look up for the meaning of the word in the medical textbooks or from any online sources.
he can understand the meaning by discussing with his colleagues.
the new words has its roots, abbreviations, suffixes and prefixes in a close proximity which makes the terminology easy and also provides quick reference.

Some of the best ways for George to learn the new vocabulary for the new position are :

George can breakdown the words in such a way that helps him to memorize the terminology less and understand more.
Learn more in details about the origin and structure of the medical terms and discuss more often with his colleagues.

A 45.0 mL sample of 0.020 M acetic acid (HC2H3O2) is titrated with 0.020 M NaOH.? Determine the pH of the solution after adding

White raven [17]

Answer:

Explanation:

CH₃COOH + NaOH = CH₃COONa + H₂O .

.02M

CH₃COOH = CH₃COO⁻ + H⁺

C xC xC

Ka = xC . xC / C = x² C

1.8 x 10⁻⁵ = x² . .02

x² = 9 x 10⁻⁴

x = 3 x 10⁻²

= .03

concentration of H⁺ = xC = .03 . .02

= 6 x 10⁻⁴ M , volume = 45 x 10⁻³ L

moles of H⁺ = 6 X 10⁻⁴ x 45 x 10⁻³

= 270 x 10⁻⁷ moles

= 2.7 x 10⁻⁵ moles

concentration of NaOH = .0200 M , volume = 35 x 10⁻³ L

moles of Na OH = 2 X 10⁻² x 35 x 10⁻³

= 70 x 10⁻⁵ moles

=

NaOH is a strong base so it will dissociate fully .

there will be neutralisation reaction between the two .

Net NaOH remaining = (70 - 2.7 ) x 10⁻⁵ moles

= 67.3 x 10⁻⁵ moles of NaOH

Total volume = 45 + 35 = 80 x 10⁻³

concentration of NaOH after neutralisation.= 67.3 x 10⁻⁵ / 80 x 10⁻³ moles / L

= 8.4125 x 10⁻³ moles / L

OH⁻ = 8.4125 x 10⁻³

H⁺ = 10⁻¹⁴ / 8.4125 x 10⁻³

= 1.1887 x 10⁻¹²

pH = - log ( 1.1887 x 10⁻¹² )

= 12 - log 1.1887

= 12 - .075

= 11.925 .

Please help Sodium (Na) has an atomic number of 11 and an atomic mass of 23. Which of the following correctly shows the electron

fredd [130]

2,8,1
It's in group 1, so its outershell only has 1 electron, and the other shells are completely filled, so 2 then 8. :)

Phosphoglucoisomerase interconverts glucose 6‑phosphate to, and from, glucose 1‑phosphate.

lawyer [7]

Answer:

Keq = 0.053

7.3 kJ/mol

Explanation:

Let's consider the following isomerization reaction.

glucose 6‑phosphate ⇄ glucose 1 - phosphate

The concentrations at equilibrium are:

[G6P] = 0.19 M

[G1P] = 0.01 M

The concentration equilibrium constant (Keq) is:

Keq = [G1P] / [G6P]

Keq = 0.01 / 0.19

Keq = 0.053

We can find the standard free energy change, ΔG°, of the reaction mixture using the following expression.

ΔG° = -R × T × lnKeq

ΔG° = -8.314 J/mol.K × 298 K × ln0.053

ΔG° = 7.3 × 10³ J/mol = 7.3 kJ/mol
