10.20 is the pH after 26.0 mL of base is added as a 25.0 mL sample of 0.150 M hypochlorous acid is titrated with a 0.150 M NaOH solution.

Define titration.

To ascertain the concentration of an identified analyte, titration is a typical laboratory technique for quantitative chemical analysis. A standard solution with a known concentration and volume is prepared as the reagent, also known as the titrant or titrator.

It is a method of chemical analysis where the amount of a sample's ingredient is determined by mixing a precisely measured amount of the desired constituent with a different substance in a precise, known proportion.

HClO + NaOH → H2O + NaClO

1.0x10⁻¹⁴ / 3.0x10⁻⁸ = 3.33x10⁻⁷ = [HClO] [OH-] / [NaClO]

[NaClO] = 0.075M

The K a of hypochlorous acid is 3.0 × 10^-8.

[HClO] = [OH-] = X

3.33x10⁻⁷ = [X] [X] / [0.075M]

X = 1.58x10⁻⁴M = [OH-]

pOH = -log [OH-] i.e. 3.80

pH = 14 - pOH = 10.20

Answer:

It is B.

Explanation:

The introduction serves to inform the reader of the basic premises, and then to state the author's thesis, or central idea. A thesis can also be used to point out the subject of each body paragraph. When a thesis essay is applied to this format, the first paragraph typically consists of a narrative hook, followed by a sentence that introduces the general theme, then another sentence narrowing the focus of the one previous. (If the author is using this format for a text-based thesis, then a sentence quoting the text, supporting the essay-writer's claim, would typically go here, along with the name of the text and the name of the author. Example: "In the book Night, Elie Wiesel says..."). After this, the author narrows the discussion of the topic by stating or identifying a problem. Often, an organizational sentence is used here to describe the layout of the paper. Finally, the last sentence of the first paragraph of such an essay would state the thesis the author is trying to prove. The thesis is often linked to a "road map" for the essay, which is basically an embedded outline stating precisely what the three body paragraphs will address and giving the items in the order of the presentation. Not to be confused with an organizational sentence, a thesis merely states "The book Night follows Elie Wiesel's journey from innocence to experience," while an organizational sentence directly states the structure and order of the essay. Basically, the thesis statement should be proven throughout the essay. In each of the three body paragraphs, one or more identified (evidence/fact/etc.) that supports the thesis statement is discussed. And in the conclusion, everything is analyzed and summed up. For example, the conclusion part in an essay about sports: "Sports can bring a bunch of benefits for youth, including general health, together with blood circulation and overall physical stamina improvement. Sport develops and improves people’s physical, social, and organizational skills, which are beneficial in personal and professional life and must always be obtained."

Since the foil has a mass of 830 g, you can use the density to find its volume 830g ⋅ 1 cm3 2.70g = 307.4 cm3 You now know that the volume of the foil is

Explanation:

The density (more precisely, the volumetric mass density; also known as specific mass), of a substance is its mass per unit volume. The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume: ρ=m/V where ρ is the density, m is the mass, and V is the volume. In some cases (for instance, in the United States oil and gas industry), density is loosely defined as its weight per unit volume, although this is scientifically inaccurate – this quantity is more specifically called specific weight.

0.03 g of ethylene glycol (C2H6O7) must be added to 1.00 kg of water to produce a solution that freezes at -5.00C.

\(\Delta T_{f} = K_{f} m\)

where,

ΔTf = Change in freezing point

Kf = molal freezing point depression constant of the solvent

m = moles of solute per kilogram of solvent.

Now,

\(\Delta T_{f} = K_{f} m\)

\(\Delta T_{f} = K_{f} \times \frac{W_2}{M_2} \times \frac{1000}{W_1}\)                 [-5.00°C = 273 + (-5.00) = 268 K] \(268 = 1.86 \times \frac{W_2}{62} \times \frac{1000}{0.001}\)                 [1.00 kg = 0.001 g]

\(W_{2} = \frac{268 \times 62 \times 0.001}{1000 \times 1.86}\)

     = 0.03 g

Thus from the above conclusion we can say that 0.03 g of ethylene glycol (C2H6O7) must be added to 1.00 kg of water to produce a solution that freezes at -5.00C.

Answer:

1192.54 J

Explanation:

Applying,

Q = cm(t₂-t₁)................ Equation 1

Where Q = Amount of heat lost, c = specific heat capacity of the iron, m = mass of the iron, t₁ = initial temperature, t₂ = final temperature.

From the question,

Given: m = 83 g = 0.083 kg, t₁ = 297 K, t₂ = 329 K

Constant: c = 449 J/kg.K

Substitute these values into equation 1

Q = 449(0.083)(329-297)

Q = 449(0.083)(32)

Q = 1192.54 J

The statement that is true about dilute and concentrated solutions is: Dilute solutions have a higher solvent-to-solute ratio than concentrated solutions.

Explanation:

In dilute solutions, the amount of solute is relatively low compared to the amount of solvent. Conversely, in concentrated solutions, the amount of solute is relatively high compared to the amount of solvent.

For example, if you add a teaspoon of sugar to a cup of water, you have a dilute solution. If you add five teaspoons of sugar to the same cup of water, you have a concentrated solution.

So, the correct statement is that dilute solutions have a higher solvent-to-solute ratio than concentrated solutions.

The biosynthesis of cholesterol is a complex process that involves multiple steps and intermediates. The pathway starts with acetyl CoA, which is converted to HMG-CoA by the enzyme HMG-CoA reductase. Mevalonate is then formed by the action of several enzymes. The next intermediates are isopentenyl pyrophosphate, geranyl pyrophosphate, and farnesyl pyrophosphate, which are formed by the condensation of several molecules of isopentenyl pyrophosphate.

Finally, lanosterol is formed from squalene through several intermediate steps, which ultimately lead to the production of cholesterol. This process is tightly regulated, and any disruption in the biosynthesis of cholesterol can lead to various diseases. In the biosynthesis of cholesterol, the correct order of the first three intermediates is: acetyl CoA → HMG-CoA → mevalonate.
The next three intermediates, in the correct order, are: isopentenyl pyrophosphate → geranyl pyrophosphate → farnesyl pyrophosphate.
The remaining intermediates to form cholesterol are: squalene → squalene epoxide → lanosterol → cholesterol.

The periosteum is a fibrous membrane that covers the outer surface of bones, excluding the joints. It is composed of connective tissue and is rich in blood vessels, nerves, and osteoblasts, cells responsible for bone growth and repair. The periosteum helps to protect bones and provides a site for muscle attachment.

The endosteum, on the other hand, is a thin layer of tissue that lines the inner surface of bones, including the spaces within bones where bone marrow is stored. It is composed of connective tissue and is rich in osteoclasts, cells that break down and resorb bone tissue. The endosteum helps to regulate the growth and repair of bones and is involved in the maintenance of bone homeostasis.
