What things are happening in the reaction tube upon changing the reaction buffer to an extremely high pH? Select all that apply
- The enzyme is denatured
- The phenolphthalein is degraded
- The phenolphthalein is denatured
- The solution turns clear
- The phenolphthalein structure is altered

Answers

Answer 1

The solution becomes clear, the enzyme is denatured, and the structure of phenolphthalein is changed.

When the reaction buffer is raised to an extremely high pH, the enzyme is denatured, the solution turns clear, and the structure of the phenolphthalein in the reaction tube is altered.

When acidic or basic compounds are added, a substance is said to be a buffer if it can resist the pH change. It may neutralise minor quantities of acid or base, essentially maintaining the solution's pH. For processes and/or reactions that require a certain and constant pH, this is essential.

These tubes provide the optimum environment for small-scale biological response or suspension culture research that need for aseptic conditions with gas exchange.

Answers

The given reaction involves the reduction of a ketone using NaBH4 and subsequent exchange of a proton with deuterium in D2O.

In the first step, NaBH4 donates a hydride ion (H-) to the carbonyl carbon of the ketone, forming an alkoxide intermediate. The hydride ion acts as a nucleophile, attacking the electrophilic carbon of the carbonyl group. In the second step, the alkoxide intermediate is protonated by D2O, leading to the formation of the corresponding alcohol and release of NaOD. The proton exchange with D2O results in the replacement of a proton by a deuterium atom. The final products are the deuterated alcohol and NaOD. The curved arrows in the mechanism represent the flow of electrons, and it is essential to show all the nonbonding electron pairs involved in each step.

A compound, C6H14, produces a 1H NMR spectrum with four dustinct signals. The steps made by the integral trace measure 21, 42, 28 and 7 mm. Complete the table below to show the number of protons associated with each signal. Integral Protons21 mm, 42 mm, 28 mm, 7 mm

Answers

Integral: Protons:

21 mm 1 proton

42 mm 2 protons

28 mm 2 protons

7 mm 3 protons

To determine the number of protons associated with each signal, we need to look at the relative areas under each peak in the NMR spectrum, which are represented by the integral trace. The integral trace values of 21, 42, 28, and 7 mm represent the relative areas under each of the four distinct signals in the NMR spectrum.

The general rule is that the area under a peak in an NMR spectrum is proportional to the number of protons giving rise to that signal. Therefore, we can assign the number of protons associated with each signal by comparing the relative sizes of the integrals.

In this case, the largest integral corresponds to the signal with 2 protons (42 mm), so we can assign 2 protons to that signal. We can then assign the number of protons associated with the other signals by using the ratio of the integrals. For example, the integral of 21 mm is roughly half the size of the 42 mm integral, so we can assign 1 proton to the signal with an integral of 21 mm.

Using this method, we can assign the number of protons associated with each signal as shown in the table above.

What is the molecular formula for a compound that is 92.24% carbon and 7.76% hydrogen and has a molar mass of 78.12g?

Answers

The empirical formula of a compound gives the whole number ratio of atoms of various elements. The molecular formula of the compound is C₆H₆.

What is Molecular formula?

The molecular formula of a compound is defined as the formula which gives the actual number of atoms of various elements present in one molecule of the compound.

Here 92.24 % 'C' = 92.24 g

7.76 % 'H' = 7.76 g

Number of moles (n) = Given mass / Molar mass

'n' of 'C' = 92.24 / 12 = 7.68 moles

'n' of 'H' = 7.76 / 1 = 7.76 g

Number of atoms of 'C' = 7.68 / 7.68 = 1

Number of atoms of 'H' = 7.76 / 7.68 = 1

So empirical formula is CH.

The molecular weight of CH = 13

Number of atoms of each element = 78.12 / 13 = 6

Thus the molecular formula is C₆H₆.

you would expect human red cells to shrink in which of the following solutions: 0.2m nacl 0.2m surcrose 0.2m urea

Answers

You would expect human red cells to shrink in  0.2 M NaCl. The correct answer is A.

Red blood cells have an ion concentration of roughly 300mM, or 300 milliosmolality. Essentially, it indicates that the concentration of all the dissolved ions in a red blood cell is roughly 300 mM, or 0.3M.

Where there is a higher concentration of water, it moves toward a lower concentration. Water flows from lower osmolarity to higher osmolarity, or put another way (since water is higher in concentration in a lower osmolarity solution).

Since a solution of 0.2M NaCl has an osmolarity of 0.4M, the water concentration in red blood cells is higher. This implies that the red blood cell will shrink and shrivel when water flows OUT of it.

Urea 0.2M is a dissolved solute even though it is not ionic. Water will somewhat enter the red blood cell since it is less concentrated than the red blood cell. (assumes red blood cells with 0.3M osmolarity).

In a hypotonic condition, a red blood cell will enlarge and go through hemolysis (burst). A red blood cell will crenate and lose water when it is placed in a hypertonic solution (shrivel). Animal cells typically function best in an isotonic environment, in which the rate of water flow into and out of the cell is equal.

Chlorine contains more Cl-37 than Cl-35

Answers

Given that the average atomic mass of a chlorine atom is 35.45 amu, then the true statement would be that Chlorine contains roughly equal amounts of Cl-35 and Cl-37. The correct answer is C.

The average atomic mass of an element is the weighted average of the masses of its naturally occurring isotopes. In the case of chlorine, the atomic mass of the two stable isotopes (chlorine-35 and chlorine-37) is close to each other.

Chlorine-35 has an atomic mass of 34.97 amu and makes up about 75% of naturally occurring chlorine atoms, while chlorine-37 has an atomic mass of 36.97 amu and makes up about 25% of naturally occurring chlorine atoms.

The average atomic mass of chlorine can be calculated using the following formula:

average atomic mass = (fractional abundance of isotope 1 x mass of isotope 1) + (fractional abundance of isotope 2 x mass of isotope 2)

average atomic mass = (0.75 x 34.97 amu) + (0.25 x 36.97 amu)

average atomic mass = 26.23 amu + 9.24 amu

average atomic mass = 35.47 amu

This is very close to the reported average atomic mass of chlorine (35.45 amu), which confirms that chlorine contains roughly equal amounts of Cl-35 and Cl-37.

The substance with the most atoms is He (10.0 g), since it has the lowest molar mass (4.00 g/mol).

What is Atom?

An atom is the basic unit of matter that is composed of three types of subatomic particles: protons, neutrons, and electrons. Atoms are incredibly small and are the building blocks of all matter in the universe.

The nucleus of an atom is made up of positively charged protons and neutral neutrons. The number of protons in an atom's nucleus determines its atomic number, which defines its unique chemical identity. The electrons, which are negatively charged, orbit the nucleus in shells and interact with other atoms to form chemical bonds.

The number of atoms in a substance is determined by its molar mass, which is the mass of one mole of the substance in grams. One mole of any substance contains Avogadro's number of atoms, which is approximately 6.022 x 10^23.

The molar masses of the given substances are:

Mg: 24.31 g/mol

Ne: 20.18 g/mol

Kr: 83.80 g/mol

Ar: 39.95 g/mol

He: 4.00 g/mol

Since the amount of each substance is the same (10.0 g), we can compare the number of atoms by comparing their molar masses. The substance with the lowest molar mass will contain the most atoms, since the same mass of that substance corresponds to a greater number of moles.

Therefore, the substance with the most atoms is He (10.0 g), since it has the lowest molar mass (4.00 g/mol).
