The painkiller, Advil® contains the active ingredient ibuprofen (IB), which has a pKb of
5.20. If the pH of a solution containing a dissolved tablet of Advil® was found to be
8.20, what was the equilibrium concentration (mol/L) of ibuprofen?

IB + H2O ⇀ IBH+ + OH−

A) 3.7 × 10−4
B) 5.5 × 10−5
C) 2.8 × 10−7
D) 4.0 × 10−7
E) 9.2 × 10−7

Answers

This problem is providing the basic dissociation constant of ibuprofen (IB) as 5.20, its pH as 8.20 and is requiring the equilibrium concentration of the aforementioned drug by giving the chemical equation at equilibrium it takes place. The obtained result turned out to be D) 4.0 × 10−7 M, according to the following work:

First of all, we set up an equilibrium expression for the given chemical equation at equilibrium, in which water is omitted for it is liquid and just aqueous species are allowed to be included:

[tex]Kb=\frac{[IBH^+][OH^-]}{[IB]}[/tex]

Next, we calculate the concentration of hydroxide ions and the Kb due to the fact that both the pH and pKb were given:

[tex]pOH=14-8.20=5.80[/tex]

[tex][OH^-]=10^{-5.8}=1.585x10^{-6}M[/tex]

[tex]Kb=10^{-5.20}=6.31x10^{-6}[/tex]

Then, since the concentration of these ions equal that of the conjugated acid of the ibuprofen (IBH⁺), we can plug in these and the Kb to obtain:

[tex]6.31x10^{-6}=\frac{(1.585x10^{-6})(1.585x10^{-6})}{[IB]}[/tex]

Finally, we solve for the equilibrium concentration of ibuprofen:

[tex][IB]=\frac{(1.585x10^{-6})(1.585x10^{-6})}{6.31x10^{-6}}=4.0x10^{-7}[/tex]

Where is the magnetic field strongest?
A. closest to the wire
B. Farthest from the wire

Answers

Answer:

In general, the magnetic field is strongest close to the wire and weaker farther away. In fact, the magnetic field weakens as 1/r1/r where rr is the distance from the wire. This can change a bit depending on the length and shape of the wire. Far enough away, the magnetic field decays as 1/r21/r2 .

You are studying the boiling points of liquids with some fellow students. You have two liquids of different molecular weights, and you test each of them twice. You find that the one with a lower molecular weight also has a lower boiling point. You would like to be more confident with the pattern you are noticing. What are two possible next steps? In one to two sentences, give specific, different examples of how the experiment could be extended, assessed, or improved.

Answers

The boiling points of two or three other pairs of liquids in which one liquid has a lower molecular mass than the other can be studied in order to see if the pattern is consistent.

The boiling point of a substance refers to the temperature at which its vapor pressure is equal to the atmospheric pressure. The boiling point of a substance has a lot to do with its molecular mass.

Generally, substances that has a higher molecular mass has a higher boiling point except other factors at at work. In order to confirm whether the pattern that you are noticing about molecular weights and boiling point is consistent, three other liquids with different molecular masses, one being higher than the other can be studied and their boiling points compared.

A sample of Ammonia gas at 650mmHg and 15 degree has a mass of 56.8g.calculate the volume occupied by the gas. Take N=14, H=1,R=8.3145jk.

Answers

Answer:

The first thing we have to do is change and state all the units so that we can use our ideal gas law equation ([tex]PV = nRT[/tex]).

650 mmHg is a pressure unit, we have to convert this to kiloPascals. We know that 760 mmHg gives us 101 kPa.

[tex]650 \ mmHg \ * \ \frac{101kPa}{760 mmHg} = 86 \ kPa[/tex]

P = 86kPa

T = 15°C + 273K = 288K

R (Gas constant) = 8.31 kj/mol  

Molar mass of Ammonia ([tex]NH_{3}[/tex]) = (1 x 3) + (14) = 17g/mol

n (moles) = [tex]\frac{mass}{molar \ mass}[/tex] [tex]= \frac{56.8}{17} =[/tex] 3.34 mol

V = ?

Rearrange the equation to solve for Volume:

[tex]V = \frac{nRT}{P}[/tex]

Substitute the values inside:

V = [tex]\frac{(3.34)(8.31)(288)}{(86)} = 93 L (rounded)[/tex]

Therefore 93 L of volume is occupied by the ammonia gas.

What is lymph nodes?

A lymph node, sometimes known as a lymphatic gland, is indeed a kidney-shaped lymphatic and immune system component. The lymphatic veins connect a massive amount of lymph nodes to one another throughout the body.

Most lymph nodes lie within the trunk adjacent to other major structures in the body - such as the paraaortic lymph nodes and the tracheobronchial lymph nodes. The lymphatic drainage patterns are different from person to person and even asymmetrical on each side of the same body. Bacteria and dead cells are removed from circulatory fluid in the lymph nodes.

How many grams of CO2 are produced using 0.29 moles of O2?

Answers

The mass of CO2 produced using 0.29 moles of O2 is 12.76 grams.

The reaction between carbon and pxygen atom is exprssed as:

C + O2 -> CO2

From he balanced equation, we can see that 1 mole O2 reacted to produce 1 mole of CO2.

Hence if 0.29 moles of CO2 was used in the reaction, the number of moles of CO2 produced will be 0.29 moles as well.

Mass of CO2 = number of moles * molar mass

Mass of CO2 = 0.29 * (12 + 32)

Mass of CO2 = 0.29 * 44

Mass of CO2 = 12.76grams

Hence the mass of CO2 produced using 0.29 moles of O2 is 12.76 grams.
