Which solutions(s) showed little or no change in pH? Why?

Answers

The buffers with high and low pH had the least change; they are buffers that resist changes in pH.

The buffer solution's pH does not change, so why not?The concentration of salt to acid (or base) remains constant after dilution for this reason. A mild acid or base that prevents abrupt pH fluctuations is a buffer.pH scales range from 7.0 and above for basic solutions to 7.0 and lower for acidic ones. Buffers are solutions that include a weak acid and its conjugate base; as a result, they can absorb too many H+ions or OH-ions, keeping the pH in the environment constant.An alkali, such as sodium hydrogen carbonate, may be used to treat a patient whose blood pH is acidotic and is 7.3.

Answers

Volume of 0.20 M sodium acetate is calculated to be 0.82g. Sodium acetate can  be used as additives in food, industry and in buffer solutions.

What is Henderson-Hasselbalch equation?

To determine  pH of a buffer is by using the Henderson–Hasselbalch equation is pH = pKₐ + log([A⁻]/[HA]).

As we know that, pH = pKa + log [salt]/[acid]  

Given pH (4.75) and  pKa (4.75).

Given [acid] = 0.20 M

When the pH = pKa, ratio of [salt]/[acid] =1 because log 1 = 0

Hence,[sodium acetate] = 0.20 M.  

4.75 = 4.75 + log [sodium acetate]/[0.20]

0 = log x/0.2

Hence, x = 0.2 M

To calculate the "amount" in grams, convert 0.20 M to grams using the volume of 50 ml (0.05 L)

0.20 mole/L x 0.05 L = 0.01 moles moles sodium acetate

what pressure of carbon dioxide is required to keep the carbon dioxide concentration in a bottle of club soda at 0.10

Answers

It takes 3.48 atm of carbon dioxide pressure to maintain the carbon dioxide concentration in a bottle of club soda at 0.10

Explain about the pressure of carbon dioxide?

Pressure on gas An under pressure liquefied gas is housed in a carbon dioxide cylinder. If heated or if the container is hydraulically full due to overfilling, it may rupture (or burst). Local laws typically govern the filling ratio of common gases.

Nondispersive infrared (NDIR) or electrochemical technology are typically used to measure carbon dioxide. The most popular method for measuring CO2 concentrations with higher accuracy over extremely wide ranges up to 100% volume is now NDIR-based carbon dioxide sensors, thanks to advancements in the technology.

Parts per million (ppm) is a unit of measurement for CO2 that represents the amount of CO2 in micromoles per mole of air. Molars per Mole (mol/mol) is the SI unit for CO2 concentration.

CO2 concentration C is 0.10 mol/L.

3.4 * 10-2 moles/L.atm for CO2 at 25 C.

Answers

The possible products of the Substitution reaction of (r)-3-chloro-3-methylhexane with methanol and heat are A and D.

The substitution reaction of (r)-3-chloro-3-methylhexane with methanol and heat is a nucleophilic substitution reaction. In this reaction, the chlorine atom in (r)-3-chloro-3-methylhexane acts as the leaving group, while the methanol serves as the nucleophile. The reaction proceeds through a series of steps:

1. The chlorine atom in (r)-3-chloro-3-methylhexane is protonated by the hydrogen atom in methanol. This creates a positively charged carbon-chlorine bond.

2. The nucleophilic attack of the methanol molecule onto the positively charged carbon-chlorine bond results in the formation of a covalent bond between the two molecules.

3. The newly formed covalent bond is then broken by the removal of the chlorine atom from the molecule, leaving behind a positively charged methoxy group.

4. The positively charged methoxy group is then protonated by the hydrogen atom in methanol, resulting in the formation of a new covalent bond between the two molecules.

5. Heat is then applied to the reaction mixture, which increases the reaction rate and facilitates the formation of the desired product, (r)-3-methyl hexane-2-methanol.

This substitution reaction is an example of a nucleophilic substitution reaction, which is a type of chemical reaction in which a nucleophile (a molecule with an electron-rich center) replaces a leaving group (a molecule with an electron-poor center) from a substrate molecule.

as seen in problem 3.109, silicon carbide nanowires of diameter d 15 nm can be grown onto a solid silicon carbide surface by carefully depositing droplets of catalyst liquid onto a flat silicon carbide substrate. silicon carbide nanowires grow upward from the deposited drops, and if the drops are deposited in a pattern, an array of nanowire fins can be grown, forming a silicon carbide nano-heat sink. consider finned and unfinned electronics packages in which an extremely small, 10 m 10 m electronics device is sandwiched between two d 100-nm-thick silicon carbide sheets. in both cases, the coolant is a dielectric liquid at 20 c. a heat transfer coefficient of h 1 105 w/m2 k exists on the top and bottom of the unfinned package and on all surfaces of the exposed silicon carbide fins, which are each l 300 nm long. each nano-heat sink includes a 200 200 array of nanofins. determine the maximum allowable heat rate that can be generated by the electronic device so that its temperature is maintained at Tt <85oC for the unfinned and finned packages.

Answers

1.30×10 W is the maximum allowable heat rate that can be generated by the electronic device to maintain the temperature below 85°C for an unfinned package.

Write the equation conduction resistance

Rcond = d/kA.........(1)

Consider the following and substitute the values:

From the table of 'thermo physical properties of selected nonmetallic solids' at a temperature of 300K.

The thermal conductivity of Silicon carbide, k is given by 490 W/m - K

Dimension of the electronic device,

W=10x10⁻⁶m

Find the cross-sectional area

A=W²

= (10x10⁻⁶)² m²

Rcond = 100×10⁻⁹/490×(10×10⁻⁶)^2

           = 2.04 K/W

The equation Convection resistance is given as follows:

Rconv = 1/hA

Consider the following and substitute the values:

Heat transfer coefficient of coolant

h= 1×10 W/m² K and

A= (10×10⁻⁶)² m²

Rcond = 1/10⁵x(10x10⁻⁶)^2

           = 1×10⁵ K/W

Find the heat rate by using the following equation

q= T1- Tinfinity/ Rcond + Rconv...........(3)

  = 2(85-20)/ (2.04+10⁵)

q  = 1.30×10 W

Thus, the maximum allowable heat rate that can be generated by the electronic device to maintain the temperature below 85°C for the unfinned package is 1.30×10 W.

What is a chemical reaction?

A chemical reaction is a procedure that causes one group of chemical components to change chemically into another. Chemical reactions, which can frequently be described by a chemical equation, traditionally include changes that only affect the locations of electrons in the formation and dissolution of chemical bonds between atoms, with no change to the nuclei.

At a specific temperature and chemical concentration, chemical reactions occur at a predictable reaction rate. Because there is more thermal energy available to attain the activation energy required to break bonds between atoms, reaction rates often increase as temperature rises.

The arrow in the reaction is telling us that what we have in the left hand side of the equation has resulted in the equation that we have on the right.

assume the magnetic susceptibility data were measured for the iron (ii) compounds given below and that the data reveals only one of them is low-spin. which of the compounds will be low-spin? hint: consult your spectrochemical series. (nh4)2[fe(h2o)6](so4)2 na4[fe(co3)3] k4[fe(cn)6] k4[fecl6] k3[fe(oxalate)3]

Answers

The low-spin compound in this set of compounds is K₄[Fe(CN)₆].

The spectrochemical series is a list of ligands ranked in order of their ability to stabilize low-spin complexes. According to the series, CN⁻ is the strongest low-spin ligand, followed by Cl⁻, CO₃⁻, and oxalate. Therefore, the compound that is most likely to be low-spin is K₄[Fe(CN)₆]. The other compounds on the list are more likely to be high-spin because the ligands they contain are weaker than CN⁻ at stabilizing low-spin complexes.

Since it is near the high-spin end of the spectrochemical series (i.e. it has a high coordination number and a high oxidation state). The other compounds in the set all have lower coordination numbers and/or lower oxidation states, so they are more likely to be high-spin.

In general, the more electrons an atom has in its outer shell, the more likely it is to be low-spin. Therefore, compounds with higher oxidation states and higher coordination numbers are more likely to be low-spin.

Hence, K₄[Fe(CN)₆] has a low spin with a strong field ligand in the spectrochemical series.

The formal charge of an atom in a Lewis structure is the charge the atom would have if all bonding electrons were shared _____ between the atoms. The formal charge doesn't necessarily reflect an actual charge on the atom.

Answers

The formal charge is a hypothetical charge assigned to an atom in a molecule assuming that all the bonded electrons are equally shared among the atoms forming the two bonds.

The formal charge is the discrepancy between the atom's number of valence electrons and the number it possesses.

Even though we frequently presume they are the same, formal charge and oxidation state are two separate concepts. While the oxidation state regulates the number of electrons exchanged between atoms during the synthesis of a molecule, the formal charge specifies the number of electrons that occur around an atom of a molecule.

When adjacent formal charges are negative or of the opposite sign, Lewis structures are preferred. The Lewis structure with the negative formal charges on the most electronegative atoms is the one to choose from when faced with a choice between numerous Lewis structures with similar formal charge distributions.

What are some differences between each of the following pairs?
a. secondary and tertiary protein structures b. essential and nonessential amino acids c. polar and nonpolar amino acids d. dipeptides and tripeptides e. an a helix and collagen f. a helix and B-pleated sheet g. tertiary and quaternary structures of proteins

Answers

The differences between each of the pair is a. secondary and tertiary protein structures of protein.

a. No sharp dividing line exists between

secondary and tertiary structures. Secondary structure refers to the spatial arrangement of amino acids close to one another on a polypeptide chain, whereas tertiary structure refers to the three-dimensional arrangement of all atoms of a polypeptide chain. Among the most important factors in maintaining 3° structure are disulfide bonds, hydrophobic interactions, hydrogen bonding, and salt linkages ; Secondary structure is mainly defines by H-bonding between amino acids in localized regions of a polypeptide or protein

b. Essential amino acids cannot be made by metabolic process of human body, Essential amino acids can be synthesized by human body.

c. The amino acids are divided into 2 categories: those with nonpolar side chains are Non-polar amino acids ( exp. Alanine, Leucine ) , and with polar side chains like acidic side chains ( Aspartic acid) , basic side chains (lysine) and -OH/-SH groups (serine) in side chains are Polar amino acids.

d. A molecule containing two amino acids joined by an amide bond (-CONH-) is called a dipeptide. Those containing 3 amino acids

are called tripeptides. ( di-, tri- indicates No. of Amino acids )

e. Collagen consists of a triple helix made of the repetitious amino acid sequences , it is tertiary structures, whereas a-Helix is Secondary structure.

f. a-Helix, is a type of secondary structure in which a section of polypeptide chain coils into a spiral, most commonly a righthanded spiral. b-Pleated sheet is also
